@wpo_chat: Let’s take a few minutes – please introduce yourself – what you do, what industry you are in etc.n #WPOchat

 
@AloisReitbauer: Question A: Is Navigation Timing ready for use in production monitoring. Some people (incl. me) had issues specifically in Firefox #wpochat

 
@wpo_chat: Remember Topics and Moderators are needed for the next chat! Leave a comment on http://t.co/cDXlL7ny Question 1 coming up. #WPOchat

 
@dritans: Is there a predefined list of questions for today’s chat? #wpochat

 
@jonathanklein: Jonathan Klein here – joining #WPOChat from Wayfair in Boston

 
 
@jonathanklein: @dritans yes, @AloisReitbauer will be tweeting them #wpochat

 
@dritans: Drit product manager with @catchpoint in NYC #wpochat

 
@AloisReitbauer: Will also tweet them heren #wpochat

 
@cweekly: Hi folks, Chris Weekly here (wearing various hats for Yottaa in Boston)n #wpochat

 
@AloisReitbauer: Question A: Is Navigation Timing ready for use in production monitoring. #wpochat

 
@jonathanklein: #wpochat A1: We use it in production, but take the data with a grain of salt (and ignore older versions of Firefox)

 
@AloisReitbauer: Question B: Which problems are you solving with real user monitoring? #wpochat

 
@AloisReitbauer: What about the lack of support in Safari. Doesn’t that hurt you guys?n #wpochat

 
@AloisReitbauer: Q3: What does your real user monitoring portfolio look like (Nav. Timing, Synthetic Monitoring, Network Sniffing)?#wpochat

 
@dritans: A1 the data has been a little iffy. Even in the browsers that support it sometime the numbers make no sense. #wpochat

 
@jonathanklein: @AloisReitbauer yeah the data isn’t complete, but it’s another data point #wpochat

 
@log_normal: hey, philip here from Log-Normal, Buddy’s here too #wpochat

 
@jonathanklein: RT @AloisReitbauer Q2: Which problems are you solving with real user monitoring? #wpochat

 
@AloisReitbauer: A1: Did you know that there is a test suite of W3C. Maybe worth reporting problems to the WG #wpochat

 
@log_normal: we use the NavTiming API, but we have a few fallbacks for where it’s not supported, (Safari, IE <= 8, Opera, iOS, Android) #wpochat

 
@jonathanklein: #wpochat A2: I think RUM is the best way to correlate performance and engagement (bounce rate, conversion rate, etc.)

 
@dritans: Can we slow down a little with the questions. I think there is like 4-5 open ones as of right now. #wpochat

 
 
@log_normal: Answer A2: we’ve also solved the Firefox problem by using alternate start times #wpochat

 
@jonathanklein: @dritans yeah that was a mistake, should be on question 2 at the moment. Question 3 will be retweeted in a few minutes #wpochat

 
@AloisReitbauer: A1: Do you think the problems are for specific sites or the implementation is instable? #wpochat

 
@dritans: RT @jonathanklein: #wpochat A2: I think RUM is the best way to correlate performance and engagement (bounce rate, conversion rate, etc.)

 
@Catchpoint: RT @jonathanklein: #wpochat A2: I think RUM is the best way to correlate performance and engagement (bounce rate, conversion rate, etc.)

 
@AloisReitbauer: @dritans We already slowed down a bit #wpochat

 
@sajal: A3: nav timing. Always facinated with network sniffing, but never implemented it #wpochat

 
@jonathanklein: @scottprice_geek you should join #wpochat - going on now! Info here: http://t.co/AnSsQ1kL

 
@jonathanklein: @dritans Got it, yeah in the past we have, this time Alois just picked the questions. We might go back to group ones in next chat #wpochat

 
@AloisReitbauer: A1: @log_normal do you feel that the values get better with newer browsers? #wpochat

 
@wpo_chat: Q3: What does your real user monitoring portfolio look like (Nav. Timing, Synthetic Monitoring, Network Sniffing)?#WPOchat

 
@cweekly: A1 Yes, “ready” w/ caveats about its fragility (i.e. take care to account for FF bug etc). GA has been using it for a long time… #wpochat

 
@log_normal: @AloisReitbauer other than the one big firefox bug, we haven’t seen any other issues, but we’re also not dependent on navtiming #wpochat

 
@cweekly: @log_normal have you documented your “alt start times” approach for FF? #wpochat

 
@log_normal: We’ve been using NavTiming in boomerang since the day IE9 added it #wpochat

 
@jonathanklein: #wpochat A3 We use Boomerang (via @log_normal) and a network tap for server side RUM

 
@log_normal: @cweekly it’s in our boomerang repo on github #wpochat

 
 
@jonathanklein: #wpochat A3 We also have synthetic monitoring through @Catchpoint

 
@AloisReitbauer: Q3: What does your real user monitoring portfolio look like #wpochat

 
@AloisReitbauer: I think boomerang is a great source of wisdom here ;-)#wpochat

 
@AloisReitbauer: A3: Where do you see the cut btw. synthetic and RUM? #wpochat

 
@bluesmoon: RT @AloisReitbauer: I think boomerang is a great source of wisdom here ;-)#wpochat

 
@AloisReitbauer: A1: I wonder how widely Nav Timing is used today. We are using it as well. Specially like the support in new mobile browsers #wpochat

 
@jonathanklein: #wpochat A3: We like having both synthetic and RUM – the former for availability/change tracking and the latter for engagement and outliers

 
@AloisReitbauer: A3: There were some discussion on synthetic to die b/c of RUM. What’s your take on this? #wpochat

 
@andydavies: @AloisReitbauer I see synthetic as being about how your servers are performing and RUM about the users experience #wpochat #wpochat

 
@AloisReitbauer: @bluesmoon you will be talking about Q3 at Velocity – right?n #wpochat

 
@log_normal: Synthetic monitoring is great to analyze object level metrics and break down requests by different network components #wpochat

 
@sajal: @AloisReitbauer synthetic will never die, there is always a need for it . esp for debugging. #wpochat

 
@jonathanklein: @AloisReitbauer RUM is a little too noisy to use on its own. Good response to Pat’s post here: http://t.co/Q56KEDiZ#wpochat

 
@AloisReitbauer: @andydavies so you do not need browser driven synthetics?n #wpochat

 
@bluesmoon: @AloisReitbauer yes, will be doing a talk with @bbrewer and Carlos Bueno from Facebook. #wpochat

 
@mrPerezMarc: has any one used new relic to monitor users speed experience?n #wpochat

 
@AloisReitbauer: @jonathanklein Agree, also RUM can never provide availability #wpochat

 
@bluesmoon: FYI Carlos is @archivd on twitter #wpochat

 
@cweekly: A3 I see them as complementary. On-demand tests and scheduled monitoring and benchmarking… real browsers + control FTW #wpochat

 
@sajal: @mrPerezMarc i find end user report on new relic to be too noisy. Its awesome for app performance #wpochat

 
@bluesmoon: @AloisReitbauer not entirely true, it’s tricky, but you can tell downtime by a significant drop in beacons (we did that at yahoo) #wpochat

 
@andydavies: @AloisReitbauer The synthetic tools I use at the moment (SiteConfidence, private WPT) are browser based.#wpochat

 
@cweekly: RT @jonathanklein: @AloisReitbauer RUM too noisy to use on its own. Good response to Pats post here:http://t.co/LuLEDHGK #wpochat

 
@AloisReitbauer: A3: I also see every big performance vendor today having both – synthetic and RUM #wpochat

 
@rockstarapps: @mrPerezMarc - we use rewrelic for server monitoring and i find our ops guys gravitate to the RUM graphs. they’re nicely integrated #wpochat

 
 
@AloisReitbauer: Q4: Do we need more. If yes – which additional information do we need?. Are you happy with Resource Timing + User Timing? #wpochat

 
@AloisReitbauer: @bluesmoon yahoo uses boomerang in production? #wpochat

 
@mrPerezMarc: @saja what do you mean by to noisy?n #wpochat

 
@jonathanklein: A4: I think resource timing will be great once it is widely supported – we need more granular timings in the browser#wpochat

 
@mrPerezMarc: What is this boomerang everyone is mentioning? #wpochat

 
@wpo_chat: Q4: Do we need more. If yes – which additional information do we need?. Are you happy with Resource Timing + User Timing? #WPOchat

 
@bluesmoon: @AloisReitbauer yahoo has been using it since 2006 #wpochat

 
 
@jonathanklein: A4: I also want really robust application level tracing for PHP *cough* dynatrace *cough* #wpochat

 
@andydavies: @jonathanklein One of the biggest problems I have with current RUM tools is the way the data is rolled up – hard to ask “what if” #wpochat

 
@cweekly: Resource timing will be very useful http://t.co/D5g5Tjmj #wpochat

 
@sajal: @mrPerezMarc I mean it doesnt give any indication of time to interact. Ad networks, widgets, etc push onload longer.#wpochat

 
@mrPerezMarc: A4 i think we need a general feel for how fast user loads pagesn #wpochat

 
 
@andydavies: @jonathanklein Using Oracle RUEI was able to distill the huge amounts of data down to meaningful stuff #wpochat

 
@mrPerezMarc: A4: i found on CNN and other sites that they mesure bandwith and deliver content based on that speedn #wpochat

 
@AloisReitbauer: What do you think about the adoption of the CORS header by Third Parties?n #wpochat

 
@dritans: Has any of the browsers has resource timing in their roadmap? #wpochat

 
@AloisReitbauer: @mrPerezMarc What should this metric look like? Isn’t that always depending on the page? #wpochat

 
@sajal: RT @dritans: Has any of the browsers has resource timing in their roadmap? #wpochat

 
@andydavies: A4 Happyish with Resource Timing there are some limitations I don’t like but understand why they are there…#wpochat

 
 
@cweekly: RT @AloisReitbauer: What do you think about the adoption of the CORS header by Third Parties? Is this Q5? #wpochat

 
@andydavies: @AloisReitbauer I we’re going to have to educate third parties on the CORS stuff #wpochat

 
@AloisReitbauer: @andydavies most of them are security/privacy relatedn #wpochat

 
@AloisReitbauer: @cweekly Part of Q4 and Resource Timing. As this would help to understand Third Parties better. #wpochat

 
@bluesmoon: @mrPerezMarc you can use boomerang to measure bandwidth. #wpochat

 
@sajal: How long would it take for resource timing to get to the point where nav timing is? wrt browser implementation.. 2 yrs?#wpochat

 
@AloisReitbauer: I mean we already get third party data today. @bluesmoon does bommerang time resources as well #wpochat

 
@andydavies: @AloisReitbauer Yeh went and read @tonygentilcore’s post to the security list asking questions about it. #wpochat

 
@mrPerezMarc: I think with all tips and tricks from @souders books, a great deal of speed modification we’ve applied proved fruitful#wpochat

 
@dritans: 3rd party providers like adserving are already doing osmething similar to CORS for flash and they do have the capabilities to do it #wpochat

 
@cweekly: @sajal I think less (vendors are rolling out new versions waay faster than they used to) #wpochat

 
@AloisReitbauer: @sajal I think Microsoft is pretty far. #wpochat

 
@bluesmoon: @AloisReitbauer kinda. boomerang lets you add timers to any part of your page #wpochat

 
@AloisReitbauer: Chrome will one of the early adopters as well I think #wpochat

 
@jonathanklein: @sajal I think Chrome and Firefox will be there much more quickly with the fast release cycle. IE…maybe in IE11?#wpochat

 
@mrPerezMarc: @cweekly, that’s the way it should be, to many people are patching up jobs and releasing site that are under constant change #wpochat

 
@jonathanklein: @ie any plans to support the resource timing spec in future browser versions? #wpochat

 
@mrPerezMarc: @sajal, could be quicker if we all submitted our ideas to w3cn #wpochat

 
@log_normal: @wpo_chat the tough part with RUM is to be able to measure and report numbers without affecting load time#wpochat

 
@AloisReitbauer: Resouce Timing Adoption – Maybe a question for this years browser panel at Velocity //cc @souders #wpochat

 
@andydavies: @jonathanklein MS are in the relevant W3C working group #wpochat

 
@dritans: RT @log_normal: @wpo_chat the tough part with RUM is to be able to measure and report numbers without affecting load time #wpochat

 
@mrPerezMarc: i find that the w3c gets a lot of collaboration from the industry #wpochat

 
@sajal: RT @AloisReitbauer: Resouce Timing Adoption – Maybe a question for this years browser panel at Velocity //cc @souders#wpochat

 
@AloisReitbauer: However browser vendors have a lot to do with the whole HTML5 thinkg ;-)  #wpochat

 
@andydavies: @log_normal That’s sort of where network taps help but obviously they don’t measure the browser experiencen#wpochat

 
@AloisReitbauer: All browser vendors are in except Apple #wpochat

 
@mrPerezMarc: why would they need to adot this, there are nifty Js code that does all this fir us #wpochat

 
@jonathanklein: RT @AloisReitbauer: Resouce Timing Adoption – Maybe a question for this years browser panel at Velocity //cc@souders #wpochat

 
@dritans: IE10 does not mention Resource Timing – so best case IE11 http://t.co/nQwfF1lJ #wpochat

 
@AloisReitbauer: Q5: What do you think about User Timing? Is manual code instrumentation the right way? #wpochat

 
@jonathanklein: @mrPerezMarc yeah but the JS has overhead and is less accurate – getting it directly from the browser is best#wpochat

 
@AloisReitbauer: A4: I think noise and meaning is a general problem in the monitoring space #wpochat

 
@andydavies: @AloisReitbauer First RUM tool I used was network tap based, you can still get a large amount of useful performance data out #wpochat

 
@cweekly: RT @andydavies: Mobile is where we really need resource timing api to be supported // TRUE #wpochat

 
@AloisReitbauer: @andydavies agree. We today managed to get Resource Timings on mobile. Custom built for sure ;-)  #wpochat

 
@mrPerezMarc: @jonathanklein A few millisecond of inaccuracy wont hurt, u will always have a margin of error #wpochat

 
@log_normal: @wpo_chat we sort of solve the noise problem by having a very large sample set (100K+) and looking at percentiles instead of amean #wpochat

 
@dritans: @andydavies afraid pple will misuse it on mobile,start posting large amnt of data for the sake of tracking #webperf making it worst #wpochat

 
@wpo_chat: Q5: What do you think about User Timing? Is manual code instrumentation the right way? #WPOchat

 
 
@log_normal: @mrPerezMarc that’s why we report margin of error with our numbers :)  #wpochat

 
@jonathanklein: RT @andydavies: Mobile is where we really need resource timing api to be supported #wpochat

 
@mrPerezMarc: @dritans tracking should be on a small scale to get a glimpse of where ythere is room from improvementn#wpochat

 
@jonathanklein: A5: I’d much rather have the data in the browser – easier to implement, more accurate, and less overhead. Every ms counts. #wpochat

 
@AloisReitbauer: We for example send back only hotspot data. Sending beacons for every resource on mobile would kill you#wpochat

 
@dritans: @mrPerezMarc totally agree, thats why our RUM solution is called Glimpse. #wpochat

 
@AloisReitbauer: @jonathanklein did you ever use a lib like User Timing? I know some people who built similar stuff. It is not really rocket science #wpochat

 
@andydavies: @mrPerezMarc But how do you know who to sample? Been thinking about a beacon for Resource Timing that you can have predicates on #wpochat

 
@AloisReitbauer: Q6: What do you think the next standard should deal with? What are we still lacking? #wpochat

 
@cweekly: RT @AloisReitbauer: … Sending beacons for every resource on mobile would kill you // Yeah, observer effect 4 mobile cld b massiv #wpochat

 
@jonathanklein: @AloisReitbauer haven’t tried it, I’m sure it’s not hard but once the data is in the browser people do a lot of great stuff with it #wpochat

 
@mrPerezMarc: @andydavies you sample who your target is, if you have clients from the us, then you sample them, or create buckets #wpochat

 
@dritans: Q6 performance of JS code. Often is not the network wire time – but badly written code that impacts end users. #wpochat

 
@AloisReitbauer: @holydevil @lognormal in RUM I feel averages have very little value. I always work with percentiles #wpochat

 
@mrPerezMarc: A6: everything & everything #wpochat

 
@AloisReitbauer: @jonathanklein. It’s not data. It is just an API ;-)  #wpochat

 
@jonathanklein: A6: That’s a tough one…perhaps a better way to sandbox third parties? Better native ways to async JS that has no dependencies? #wpochat

 
@AloisReitbauer: @dritans That’s what User Timing should do … #wpochat

 
@AloisReitbauer: @mrPerezMarc everything is bit unspecific ;-)  #wpochat

 
@mrPerezMarc: @dritans Js will always be a problem bcause everyone does it differently. have you ever used JsLink?n #wpochat

 
@jonathanklein: @AloisReitbauer haha, fine. Maybe I’m just lazy (busy?) #wpochat

 
@AloisReitbauer: @jonathanklein. I think the performance sandboxing is a great idea. You should post that to the WG #wpochat

 
@andydavies: Q6 – media queries for more things e.g. SVG, better way of determining the browser characteristics on the server#wpochat

 
@dritans: @AloisReitbauer RUM or not, when measuring web performance averages will lie. Too many factors intertwined #wpochat

 
@wpo_chat: Q6: What do you think the next standard should deal with? What are we still lacking? #WPOchat

 
@cweekly: @jonathanklein @AloisReitbauer … also User Timing has better precision (so it’s not just a convenience for implementation) #wpochat

 
@AloisReitbauer: Q7: Which timings to you look at? Is onLoad still relevant. What timings do you track? #wpochat

 
@bluesmoon: @wpo_chat I’d really like to see measurements for rendering time, CSS, layout, etc. #wpochat

 
@mrPerezMarc: @AloisReitbauer Ok fine… including the kitchen sink. the big problem i find is that their are great ressources on how to speed #wpochat

 
@mrPerezMarc: @AloisReitbauer speed up sites, but 90% of ppl dont do it. #wpochat

 
@AloisReitbauer: @cweekly agreed. Just as performance.now() will have #wpochat

 
@jonathanklein: @dritans @AloisReitbauer yeah but those people at the 95th percentile make your site look SLOW </sarcasm>#wpochat

 
@wpo_chat: RT @AloisReitbauer: Q7: Which timings to you look at? Is onLoad still relevant. What timings do you track? #WPOchat

 
@andydavies: Sorry got to jump out will read back through the thread later #wpochat

 
@jonathanklein: RT @bluesmoon: @wpo_chat I’d really like to see measurements for rendering time, CSS, layout, etc. #wpochat

 
@mrPerezMarc: @AloisReitbauer A7, mainly everything before onLoad, because until then, most users can’t do anything, and post is all extra stuff #wpochat

 
@AloisReitbauer: @bluesmoon good point. How deep should that go. We are still in prod monitoring here …. #wpochat

 
@dritans: Q6 Onload is still relevant for most sites. On newer sites relying on AJAX/HTML5 it can be useless #wpochat

 
@jonathanklein: A7: TTFB is always a good one, onLoad still matters but you can game it. #wpochat

 
@cweekly: @dritans ”Often is not the network wire time – but badly written code…” // This is the 90/10 lesson of WPO all over again :)  #wpochat

 
@bluesmoon: RT @jonathanklein: @dritans @AloisReitbauer yeah but those people at the 95th percentile make your site look SLOW </sarcasm> #wpochat

 
@AloisReitbauer: What about above the fold? #wpochat

 
@AloisReitbauer: RT @bluesmoon: yeah but those people at the 95th percentile make your site look SLOW </sarcasm> #wpochat

 
@bluesmoon: @jonathanklein if you’re gaming your own performance numbers, then performance is not your problem ;)  #wpochat

 
@dritans: @jonathanklein the question abt 95% is are they there because of crappy router, downloading lots of torrents,or ur site hated them #wpochat

 
@jonathanklein: @AloisReitbauer Yeah could be nice, but hard to measure and fold is different for all. When the browser provides it natively… :-)  #wpochat

 
@AloisReitbauer: @cweekly If it is the code, then we need better devs ;-)  #wpochat

 
@dritans: RT @bluesmoon: if youre gaming your own performance numbers, then performance is not your problem ;)  #wpochat

 
@holydevil: @aloisreitbauer onLoad – yes. To be precise, it’s ‘time to interact’ that’s important. There’s no standard way to measure this. #wpochat

 
@AloisReitbauer: Q8: What do you think about the missing ability to measure bandwitdh? #wpochat

 
@bluesmoon: @AloisReitbauer boomerang already has bandwidth measurement ;)  #wpochat

 
@wpo_chat: RT @AloisReitbauer: Q8: What do you think about the missing ability to measure bandwitdh? #WPOchat

 
@jonathanklein: A8: Well it’s not missing in Boomerang, but a native way is. It’s hard to do without making people download a series of files #wpochat

 
@AloisReitbauer: @bluesmoon by downloading images – right? #wpochat

 
@jonathanklein: RT @AloisReitbauer: Q8: What do you think about the missing ability to measure bandwitdh? #wpochat

 
@dritans: A8. Not sure if we need bandwidth, or something else. We need an indicator if the user is having network issues across the board. #wpochat

 
@AloisReitbauer: Shouldn’t browsers just provide this info. They have it. #wpochat

 
 
@jonathanklein: A8: So I doubt browsers will add that functionality #wpochat

 
@bluesmoon: @AloisReitbauer so you can already get mobile connection type from Android devices #wpochat

 
@AloisReitbauer: I hate to do that image thing on mobile. Especially in Europe with all the costly roaming plans ;-)  #wpochat

 
@jonathanklein: @AloisReitbauer Do the browsers have it? How? They can estimate it…but it’s not super precise if resources are small #wpochat

 
@AloisReitbauer: You can kind of estimate it with Nav Timing as well #wpochat

 
@log_normal: We also record information from the Network Information API: http://t.co/De7FzKOc #wpochat

 
@dritans: At home my connection could say cable, but at 9PM its the equivalent of a modem. What consumers purchase is not what they get. #wpochat

 
@mrPerezMarc: @dritans what if an issue with 1-5% of ur visitors, should u spend that much time effort money 2 make sure they are well servered?n #wpochat

 
@AloisReitbauer: @bluesmoon agreed. Unfortunately that does not tell us what it really is. I now some 3G connections that are faster than WiFi ;-)  #wpochat

 
 
@bluesmoon: You can also buy a bandwidth database from MaxMind or Quova to tell (sort of) Bandwidth based on IP #wpochat

 
@dritans: @mrPerezMarc depends on who that 5% is, what if it is the one that bring 80% of your revenue? #wpochat

 
@AloisReitbauer: @mrPerezMarc What if they buy your stuff? Isn’t this why we all do it? #wpochat

 
@jonathanklein: @bluesmoon Is that based on purchased bandwidth or actual bandwidth? #wpochat

 
@cweekly: @dritans … right — to say nothing of mobile users. “bandwidth” is increasingly dynamic… #wpochat

 
@mrPerezMarc: @AloisReitbauer if the 5% are the ones buying my stuff, then their really isn’t a problem with my site is there?#wpochat

 
@dritans: FCC study clearly shows there is problems with consumer networks. They do degrade way below what is promisedhttp://t.co/LDSiJxdV #wpochat

 
@bluesmoon: @jonathanklein it’s based on advertised bandwidth, which may not even be the same as purchased bandwidth#wpochat

 
@wpo_chat: You are welcome to keep chatting as we come to a close. Great conversation going here with the #WebPerf community. #WPOchat

 
@mrPerezMarc: @dritans then for them, they accept my site the way it is and gladly spend their money #wpochat

 
@wpo_chat: Did you enjoy this chat? Do you have any suggestions? #wpochat#WPOchat

 
@cweekly: I’ve gotta bail. Great chat guys, see you all next time! n #wpochat

 
@wpo_chat: Remember – Topics, Moderators, Guests, Wanted – If that’s you leave a comment on http://t.co/cDXlL7ny #WPOchat

 
@AloisReitbauer: In Europe they now slow you down when over your data limit. Also a point #wpochat

 
@mrPerezMarc: @AloisReitbauer @dritans users have multiple devices, pc, ipads, phones, so if the site is fast enough on one they know it’s them #wpochat

 
@log_normal: @wpo_chat BTW, 54% of you who visited our site today have a network speed between 2-6Mbps #wpochat

Announcing the next #WPOchat – Moderated by Alois Reitbauer WED 3-21-2012 1pm ET

Monday, 5. March 2012 - 10:42 pm | View Comments

Announcing the next #WPOChat – a Twitter chat for Web Performance Optimization professionals.  The chat will be held on Twitter with the hashtag of #WPOchat

NEW DATE: Wednesday March 21, 2012 1pm ET. (Really!)

This time is friendly for Europe, a post-lunch break in ET and a late morning in PT.

(Rescheduled from  Mon 3/19 and Tue 3-13, postponed due to moderator illness and scheduling issues. It’s DEFINITELY ON for 3/21.)  

Topic:

Navigation Timing is the first standard of a number of emerging standards from the W3C Web Performance Working Group. It provides easy access to browser based performance metrics of real users. How will real user/user experience monitoring change and what are you already doing today? During this WPO chat we will discuss the following questions:

Are you already using Navigation Timing and how?

  1. Is Navigation Timing production ready?
  2. Do we need more. If yes – which additional information do we need?
  3. Which problems are you solving with real user monitoring?
  4. What does your real user monitoring portfolio look like (Nav. Timing, Synthetic Monitoring, Network Sniffing)?

bluesmoon @wpo_chat an app cache is good for public data. For user private data (login required) security becomes more imp than performance #wpochat -3:18 PM Jul 25th, 2011


wpo_chat Q3 Besides app cache, what other performance optimizations are most important for mobile? #wpochat -3:18 PM Jul 25th, 2011


dcmouyard @mrPerezMarc Aggregating & minifying scripts/styles shouldn’t increase load time. #wpochat -3:18 PM Jul 25th, 2011


jonathanklein @wpo_chat #wpochat @bryanmcquade This brings up another question – when to pre-fetch and when to use app cache? -3:18 PM Jul 25th, 2011


bryanmcquade A2 a single failure (e.g. a single redirect for any of the resources on the page) means the whole app cache is invalid.#wpochat -3:18 PM Jul 25th, 2011


bluesmoon @wpo_chat I’ve written code on bluesmoon.info that overrides document.write to allow async loading of third party widgets #wpochat -3:17 PM Jul 25th, 2011

bryanmcquade A1 @cranstone is this on the oldest Android devices (e.g. G1) or also on recent devices? Is it CPU bottleneck or bad gzip impl? #wpochat -3:12 PM Jul 25th, 2011


coachwei @patmeenan They do slow down quite a bit because each widget typically results in meay requests. #wpochat -3:12 PM Jul 25th, 2011


joshuabixby @bryanmcquade @coachwei A1 3rd party content is a bit of a wild card. First step is to analyze waterfall and find culprits. #wpochat -3:11 PM Jul 25th, 2011


mrPerezMarc @dcmouyard A1: I’ve noticed that, as well, but how do we go about solving these issues? #wpochat -3:11 PM Jul 25th, 2011


hsimon @bryanmcquade @coachwei don’t copy&paste the tutorial code, consider async loading as late as possible #wpochat -3:11 PM Jul 25th, 2011


dcmouyard A1: The solution is aggregation & minification of images, scripts, and stylesheets. #wpochat -3:11 PM Jul 25th, 2011


jonathanklein @wpo_chat #wpochat A1 totally agree on 3rd party content, those are HTTP request you can’t really control -3:11 PM Jul 25th, 2011


mrPerezMarc @cweekly kinda hard to tell that to a dev team#wpochat -3:10 PM Jul 25th, 2011


patmeenan @wpo_chat A1 do the widgets REALLY slow down the sites much (loaded async) or do they just push onLoad?#wpochat -3:10 PM Jul 25th, 2011


dcmouyard A1: The biggest performance bottleneck for CMS implementations is usually the size & number of HTTP requests.#wpochat -3:10 PM Jul 25th, 2011

jonathanklein @mrPerezMarc @wpo_chat I like synthetic tools (we use Catchpoint) + RUM tools (we use Coradiant). There are free versions as well #wpochat -3:08 PM Jul 25th, 2011


getify @wpo_chat A1: … so, use a script loader that is performance oriented. like perhaps LABjs. :)  #wpochat -3:08 PM Jul 25th, 2011

Archive of 6-27-2011 #WPOchat – Moderated by Aaron Peters

Thanks everyone for another great #WPOchat Twitter chat.  With Velocity earlier in the month and all of the recent focus on Web performance in the press, it seems that we are all members of a fast growing industry.

This month’s moderator was Aaron Peters (@aaronpeters) He selected questions from the community via the Google Moderator site.  Thanks Aaron – your support was great.

Stay tuned for next months chat topic and moderator announcement. The next chat is scheduled for Monday July 25th at 3pm ET or 8pm London.

Time – we had a smaller turn-out this month which may be due to the time or lack of awareness.  Turn-out from the EU was good as 3pm ET is a better time for people in the EU.

Here is a copy/past of the #WPOchat Twitter chat.
