Startup Performance

Estimated win Bug # Summary Owner Status Notes
~10% "Dirty Profile" Startup Reduction Constant startup relative to profile size Shawn Wilsher
significant bug 558200 Extension profiler platform api Steve Fink There is an easy way to provide feedback to extension developers to help them figure out why their extension is misbehaving. We need to implement that ASAP, so typical firefox installs(with lots of extensions) can be fast

Highlights from the weekly update post:

  • Taras is working on library IO, and posted some details and optimization approaches, and posted a log of what's loaded and how long it takes.
  • The new cold startup graphs are here for Mac and Linux.
  • I've made progress on emulating cold startup on Windows, more details on the weekly update post linked above.
  • Rob Strong has been making a bunch of changes in the update system, which can improve startup time on mobile, and posted a list of the changes.
  • Drew has a patch up for bug 506814, getting rid of GetPersistentDescriptor/SetPersistentDescriptor on Mac, needs review from Josh.
  • Ben Hsieh has been prototyping a whole Fastload cache replacement in bug 520309.

Tree Management

  • Split mochitests landed. Thanks to all who helped out. As a result we were able to un-hide some of the debug test columns (most of linux and windows unhidden)
  • Running mochitest-ipcplugins on Electrolysis
  • Running jsreftest, and check-valgrind on Tracemonkey
  • The minipocalypse is upon us!
    • We can no longer buy 1.8 GHz minis, which are the common hardware platform for all our Talos machines
    • Thanks to all who have donated their old minis!
    • We are evaluating the current generation of minis. Need to give some thought to where these will get deployed. New test platforms only (Snow Leopard, Win 7)? New branches only? New tests only? How important is it that we have the same hardware platform across all OSes?


  • list of crashes by group (estimates) coming soon; please review it and see if there are crashes you can fix!
  • Any objection to bug 518003 landing on 1.9.2? How about renaming the method from mozMatchesSelector to simply matchesSelector?
