Performance

• This week's Snappy summary

• SUMO alerted us that they've received feedback that Firefox 15 Beta loads pages slower than 14. If you can reproduce a performance regression to do with loading webpages/games/etc in FF15 vs FF14, please comment in bug 784512.

• Tim landed the new thumbnail storage so that we can finally remove the file cache usage for thumbnails (bug 754671)
• Tim also landed preloading new tab pages in the background (bug 753448) - currently preffed off
• Jon Coppeard landed incremental sweeping for the atoms table (bug 779183)
• Benoit made a number of changes to the profiler
  • Added JS source view
  • Cleopatra selection will persist when changing the filter, and several minor bug fixes
  • JS only view will now filter c++ frames
  • Column info landed in the JS engine. Hoping to get it exposed to profiling and then we can work toward deminifying JS script. This should help diagnose some problems with sites like Twitter.
  • JS profiling protocol is close to landing. This will let us profile nightly/release build of Fennec, let us control features and settings which are built time right now. This will help for b2g as well.

Layout

• display list-based invalidation close to relanding (try builds available for testing, see comment 280 in bug)
• Bugs of interest:
  • async (off-main-thread) animations enabled in content processes (bug 785657)
