Performance/Status Meetings/2007-June-06

« Back to Status Meetings

Agenda

• Choosing time/frequency of meeting: 10am-11am? Every week?
• Generate reliable, relevant performance data (already underway as talos). Talos status update?
• Graph server status
• Areas where help is needed
• Reducing test variance

• expand the scope of performance testing beyond Ts/Tp/TXUL/TDHMTL
• reduce noise in tests to ~1% (suggested by bz, not started)
• run performance tests with profiling on (rhelmer set up a machine for this, but jprof has problems on trunk)
• move perf tests to chrome, so we get more reliable results, and

can test more than just content

• improve performance reporting and analyses:
• Graph server for easy build-to-build comparisons
• Better reports for sheriffs to easily spot perf regressions
• Tracking down specific performance issues
• stats change to track AUS usage by osversion.

• New ideas

Action Items

• Preed: Assist Robcc with BB Master instance (use ref plat)
  • preed: handed ref image to ????. Back and forth questions on what was/wasnt needed. Some issues about setting up developer instance on local machine in addition to server image. AI:preed to meet offline robcee.
• Alice/Robcc: File bugs/bullet list of areas others could help for perf infra
  • AI:alice: collected info on personal webpage, will post to public server soon
• Justin & rhelmer: hardware for JProf
  • AI:rhelmer reopened bug 366615
• Getting higher resolution timers for tests
  • AI:Damon will meet with Boris about this. Different issues on different platforms.

Other Information

Priorities for infra:

• Get farm up with new machines reporting data for trunk
  • AI:Robcee configuring machines with Alice, expecting to have machines reporting this afternoon.
• 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
