Sorry for the delay in getting this posted.

Summary:

• We pushed 1,134 code changes to our mercurial-based repos. This translates into 12,345 build/unittest jobs, or ~16.6 jobs per hour, over the month.
• We hit 108 pushes on May 19th. This is a new high-water-mark, by far the biggest load in any one single day since we start measuring. This was the rush of checkins to beat the mid-May code freeze date.
• Mozilla-191 and TryServer now does linux-arm and WinMo builds, which creates extra load per push.
• The mozilla-1.9.1 branch was more active then usual, as expected in the lead up to FF3.5.0 release.
• The chart below shows no data for TryServer for the week of 1st – 7th May. This was because of our resetting of the repo, and is expected. The TryServer was up and being used, but this means TryServer numbers are too low.
• We’re still not measuring load on Talos yet.

Details:

As each of these pushes triggers multiple different types of builds/unittest jobs, the *theoretical* total amount of work done by the pool-of-slaves in May was 12,345 jobs. For each push, we do:

• mozilla-central: 12 jobs per push (L/M/W opt, L/M/W leaktest, L/M/W unittest, linux64 opt, linux-arm, WinMo)
• mozilla-1.9.1: 12 jobs per push (L/M/W opt, L/M/W leaktest, L/M/W unittest, linux64 opt, linux-arm, WinMo)
• tracemonkey: 7 jobs per push (L/M/W opt, L/M/W unittest, linux64 opt)
• try: 9 jobs per push (L/M/W opt, L/M/W leaktest, L/M/W unittest)
• theoretical total: (523 x 12) + (282 x 12) + (138 x 7) + (191 x 9) = 12,345 jobs per month = 16.6 jobs per hour.

UPDATE: TryServer supported for linux-arm and WinMo were enabled in the last few days of the month, so I’ve excluded them from the math, and recalculated number-of-jobs.  John. 17July2009
