<trackbot> Meeting: Web Performance Working Group Teleconference

<trackbot> Date: 29 February 2012

<dmandelin> I just dialed in too

<scribe> scribe: jatinder

<Alois> Dialed in

High Resolution Time

Jatinder: Was there any feedback to the spec?

<dmandelin> the users i talked to didn't seem to need to know the resolution, they just wanted to get the best resolution the system could provide

Tony: There was some feedback on the definition of the start of navigation. We should use navigationStart.

Jatinder: I agree that we should tie the definition in with navigationStart.

James: Regarding the minimum resolution, I think we should just leave it as a best effort.

<plh> I'm ok with best effort

Tony: I like it how it is.
... Boris had raised concerns on requestAnimationFrame?

Jatinder: I had responded on the thread. Seeing that developers were aware that they were using prefixed code that could still change behavior and requestAnimationFrame spec has only now just gone into Last Call, I don't think it's too late to make such changes.

Tony: What about performance.timing attributes?

Jatinder: They will remain as is. When using getEntries() you will get the new time.

Resource Timing

Jatinder: http://www.w3.org/2012/02/resource-timing-lc-issues.html

http://lists.w3.org/Archives/Public/public-web-perf/2011Aug/0021.html

plh: Jatinder why don't you review the lists and get back to the mailing list if there are any issues.

Jatinder: Definitely.

Karen: What about mailing list discussions on iframe security?

Tony: We had closed that by saying we were going to use navigationStart.

Jatinder: I wrote a section on statistical fingerprinting. Seeing that cache hits and misses can be determined without sub-millisecond resolution.

James: We should continue the discussion with our security folks and close on this.
