Summary:

• Overall, total numbers approx the same as last month. However, it is interesting to see fewer checkins on mozilla-central, but a significant increase in mozilla-191, mozilla-192 checkins. I suspect this is caused by increased focus on security releases and the upcoming FF3.6 release. The increased load on try is probably also related to this.
• The numbers for this month are:
• 1,675 code changes to our mercurial-based repos, which triggered:
• 20,029 build jobs, or ~84 jobs per hour.
• 40,421 unittest jobs, or ~56 jobs per hour.
• 41,467 talos jobs, or ~58 talos jobs per hour.
• 18th November was our third busiest day of the year, with 103 checkins. For comparison, this high level was only exceeded on 22nd Sept (116 checkins) and 20th May (108 checkins).
• We enabled new Talos suites, and also disabled some unittest suites at different times during the month. For simplicity, I’ve ignored those changes for now, and will include in next month’s data.
• We are still not tracking down any l10n repacks, nightly builds, release builds or any “idle-timer” builds.

Here’s how it looks compared to the year so far:

Here’s how the math works out:

The types of build, unittest and performance jobs triggered by each individual push are best described here.
