Startup Performance

Summmary

Priorities

Estimated win Bug # Summary Owner Status Notes
>10% bug 512584 Super fast paths for Components.classes and Components.interfaces Taras Glek in progress Got consultation from mrbkap, needs new patch.
>10% bug 525013 Investigate a more static build configuration of Firefox Joel Reymont Mac and Linux in progress Only measured on Mac so far, need Linux numbers and someone to figure out the Windows story.
up to 25% bug 514083 Per-file HFS+ compression on Mac OSX 10.6 Joel Reymont in progress Snow Leopard only.
TBD bug 520309 Startup cache: replacement for fastload cache Ben Hsieh review More efficient than current fastload, and key to enabling fastloading of XBL, CSS, manifests and various other data. Need to push to Places branch to figure out base perf difference from current fastload.
TBD bug 503483 Turn on –enable-faststart for Firefox by default Dietrich needs testing Loads Firefox core libraries at boot time. Need to test on all OSes, publish the numbers, and get discussion going.

Security

Electrolysis

  • OOPP has landed and appears to have stuck!
  • Minor issues abound (IPC on only): e.g. any plugins installed to a path with spaces are broken
  • Need to get Talos changes landed (bug 529137) so that we can enable OOPP by default on E10s tree, and then once blockers are fixed, on mozilla-central (blocker tracking).

To turn on IPC plugins, set the pref dom.ipc.plugins.enabled in nightlies starting this morning.

Tree Management

  • Stopped sending test results to *-Unittest trees. bug 534252 Scraping will need to be turned on as new columns show up.
  • Enabled mochitest-ipcplugins tests on m-c, places, tracemonkey bug 530522
  • Turned on optimized and debug packaged tests on tracemonkey bug 524176
  • Still need to do extended downtime so IT can do database maintenance bug 528573. All trees that report to talos will be need to be closed.

Roundtable

  • Need to discuss adding a null deref to make add-ons fail early, i.e., Relevant Knowledge uses the a11y API in a non-threadsafe way. We should block the dlls, but also keep add-on developers from using this in a way that will eventually crash. The problem is we don’t know how many add-ons this will break (and will it matter?). Also, is there a patch ready to make this happen? If not, can we get one ready so that we are prepared to pull the trigger? Peterv has the details. (damons)
