Startup Performance

Highlights from the weekly update post, and work started this week:

• John Dagget's ~20% cold startup improvement and ~4% warm startup improvement on Mac in bug 517045 landed on branch.
• Taras Glek’s work on combining the different preference files has landed (bug 507288)
• Alfred Kayser’s patch to increase throughput of JAR file reading has landed (bug 510844).
• Ryan landed bug 475289 to lazily initialize the engineMetadataService for an expected 20ms win.
• Ben Hsieh got some stat() removal landed in bug 510991. He's got even more in bug 511761, just need bsmedberg review.
• I’m no longer able to reproduce the Windows cold startup regression from 3.5 to 3.6 reported in bug 517741. I turned off SuperFetch, which resulted in more stable numbers, but there was no visible regression, even in builds going back a couple of months. Juan tested on Windows XP and found the same. The current numbers show a 27-30% *improvement* in cold startup time on trunk, and up to 8% on 3.6.

Security

Nothing to report.

Electrolysis

• Windowless plugins animating correctly (implement NPN_Invalidate*)
  • karlt beginning to design asynchronous painting
• Remote canvas.drawWindow in final review. Yay!
  • Now we need to get event handling back up to speed
• NPRuntime in final review
• bent working on Windows deadlocks

Tree Management

• We need a quiet time to land split-mochitests so we can iron out inter-test dependencies. Post-beta?

• Win7 SDK is deployed!

• Migrating 8 Tiger Talos machines to run Linux / Vista on Try Talos

• Turning off idle builds. We currently run a full set of builds and tests if nothing on a branch has changed in several hours. This ties up resources required for other branches.

• 1,774 landings last month, 37% jump over previous recorded highest
  • year to date range: 1,018 to 1,295
