Infrastructure load for September 2010

Summary:

There were 2,436 pushes in September 2010. This is below the record of 2,707 in August. I note Sept 15th set a new record of 160 pushes in one day.

Overall load since Jan 2009The numbers for this month are:

  • 2,707 code changes to our mercurial-based repos, which triggered 336,910 jobs:
  • 46,175 build jobs, or ~64 jobs per hour.
  • 145,509 unittest jobs, or ~202 jobs per hour.
  • 115,608 talos jobs, or ~160 talos jobs per hour.

Yet again, TryServer continues to be almost half the load of all branches combined on the entire infrastructure.Infrastructure load by branch

Details:

  • September 15th set a new record high of 160 pushes in a single day!
  • We are still double-running unittests for some OS; running unittest-on-builder and also unittest-on-tester. This continues while developers and QA work through the issues. Whenever unittest-on-test-machine is live and green, we disable unittest-on-builders to reduce wait times for builds. Any help with these tests would be great!
  • The entire series of these infrastructure load blogposts can be found here.
  • We are still not tracking down any l10n repacks, nightly builds, release builds or any “idle-timer” builds.

Detailed breakdown is :
