Participants

Agenda

Action Items

  • AT:alice/robcee will continue historical runs back to branch date of 12aug2005.
  • AI:alice to write script to copy files after build,
  • AI:joduinn meet with robee, rhelmer, zach, alice to figure out buildbot slave-in-talos issues.
  • AI:alice/robcee will continue historical runs back to branch date of 12aug2005.
  • AI:justin stats change to track AUS usage by osversion. bug 382044.
  • AI:rob arnold proxy-server work bug 389703
  • AI:damon how are we tracking perf bugs?

Infrastructure

  • Talos status update? http://tinderbox.mozilla.org/MozillaTest/
    • Mac Port status?
    • New Vlad Tp test status?
      • Decided we'd switch over to new Tp runner on new hardware (pageset v2) and then make sure it was stable

Gecko: Perf discussion

  • Perfathon update
    • vlad has data, wants to provide Mac data, but is blocking on cairo (because otherwise the topmost stuff by far is random cairo rendering that's fixed)


  • probe update
    • module owners should let stan know if they have any situations that they'd like to analyze, so that he has more information about how to structure the probe work.

Previous weeks

  • Discuss talos cpu usage metric
    • cpu usage numbers... discussion on how cpu usage being calculated.
    • going to ignore those numbers for now, no humans looking at them.
    • qm-pmac04 setup as a buildbot slave as per the mac test ref platform, but not yet hooked up to the master.
  • Areas where help is needed
  • expand the scope of performance testing beyond Ts/Tp/TXUL/TDHMTL
  • reduce noise in tests
    • reduce to ~1% (suggested by bz, not started)
    • some hardware for large-sample-set-Tp-100times-per-page
    • havent had time for buildbot integration, not needed.
  • improve performance reporting and analyses:
    • Better reports for sheriffs to easily spot perf regressions
    • Tracking down specific performance issues
  • Priorities for infra:
    • Generate historical baselines
    • General profile data regularly on builds
    • Getting the perf numbers more stable
    • Developing the graph server to display time spent in each module
  • jrpof tinderbox
  • synthetic tests (TODO)
    • put specific tests into talos framework
    • poach mochitest performance tests
    • individual reftest-like items
  • need to get a bunch of people looking at profiles (TODO)
    • take up some of these meetings to sit down and look at profiles
    • timer-based profiling is better (vtune/jprof/oprofile/etc., not quantify)
    • TODO: vlad to generate profile for next week's meeting
  • running without Fx chrome
    • new pageloader stuff can do this
  • examining default theme for performance issues
  • Tp vs. Tp2
    • new pageloader stuff avoids this problem
    • Tp2 was flawed in some ways -- one big one is that it loaded pages in an iframe, so initial paint delay was never coming into play, and we were potentially reflowing more thannecessary
