I'll look at the resource timing tests later 18:09:08 ... I'll move the user timing tests 18:09:43 Topic: Resource Timing cross origin redirect 18:10:29 Jatinder: I'll respond to Pan on that. Didn't close on what to do yet. I think he has a point on per resource point 18:10:42 Topic: Navigation Timing 2 18:10:58 Jatinder: one of the goal is perceive latency and with pre-render, the latency changes 18:11:15 ... should we add an attribute preRenderSwitch to NV2? 18:11:55 ... today, we get duration. would be interesting to have the delta between loadEvent and preRenderSwitch 18:12:07 ... it seems logical to me at least 18:12:24 James: sounds good to me. it ties into page visibility as well 18:12:48 Jatinder: we should make it clear that this is not real time performance but rather data to understand page load performance 18:12:54 Zakim-bot will be restarted in 3 minutes to recover caller state; please save your agenda status. Apologies for the inconvenience 18:13:12 ... I'll follow up by mail 18:13:25 ... we'll have to be careful on how preRenderSwitch will come off 18:13:39 Topic: Beacon API 18:13:52 Jatinder: sent mail about this regarding the relationship with XHR 18:14:11 ... so we don't have to reinvent everything 18:14:23 ... seems like there is interest 18:14:41 ... I was hoping we can continue exploring, so let's not cut it from our list 18:14:53 ... in a perfect world, I would love to have XHR take it on 18:15:15 Alois: yes, this would require some input from our side. let's try to reuse here 18:15:25 ... hopefully it will get into XHR 18:16:38 Jatinder: it seems we'll need to provide guidance to them 18:16:45 ... we'll send them a proposal 18:17:07 Topic: Prerender 18:17:15 Arvind: I started to write it 18:17:39 Jatinder: I have a bunch of questions and will hold until you come up with something 18:19:26 Arvind: two ways, link tag and when the browser does it (like typing in the address bar) 18:19:37 ... I'm focusing with the link tag 18:19:52 Jatinder: yes, I don't think we should define heuristic indeeed 18:20:08 ... should we say that "user agents can use heuristics" ? 18:20:28 ... should we say something about prerendering https? 18:20:39 Arvind: we waited to avoid side effect 18:20:54 Daniel: do we have data on side effects? 18:21:03 Arvind: not really, I'll follow up 18:21:24 Jatinder: should we leave the spec open or not? 18:22:01 ... also a performance impact. Should we put limits? 18:22:24 ... it seems logical to one, rather than the whole result page 18:22:42 Arvind: ok, I'll keep working on it 18:23:28 Jatinder: if you can share the documentation you have, that would be nice 18:23:36 Zakim has joined #webperf 18:23:39 Topic: other specs 18:23:41 Jatinder: resource priorities, diagnostic 18:26:14 Topic: Page Visibility, RAF 18:26:18 Plh: we're on track 18:31:10 Topic: Milestones 18:31:20 Plh: are the milestones correct? 18:31:25 Arvind, Jatinder: yes 18:31:47 Topic: bandwidth testing issue 18:32:27 Jatinder: the nav timing is post processing, while bandwidth is for real time decision 18:32:39 ... nav timing isn't a real time api 18:32:58 Daniel: I've been writing some thoughts and will send them along 18:33:30 Plh: should it go into XHR? 18:33:40 Daniel: up for discussion. 18:34:21 [adjourned] 18:34:37 rrsagent, generate minutes 18:34:37 I have made the request to generate http://www.w3.org/2013/02/13-webperf-minutes.html plh 20:29:24 jeffh has joined #webperf 21:42:31 Zakim has left #webperf
