Action Item Update
Agenda
- Choosing time/frequency of meeting: 10am-11am?
- Talos status
- Graph server status
- Areas where help is needed
- Reducing test variance
- New ideas
Agenda:
- Extending meeting? Maybe 10-11?
- generate reliable, relevant performance data (already underway as talos)
- 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
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
