Performance

  • This week's Snappy summary
    • What we learned about Windows Prefetch from Telemetry
  • Jeff Muizelaar wrote an interesting blog post work involved in a tab switch on Mac.
  • A number of cache improvements from Necko team have landed and some more are coming soon from bbondy.

GFX

JS

Layout

  • met in person last week (with Graphics and Video)
  • SVG display lists landed, pref'ed off
    • makes painting and hit-testing for SVG work much more like it does for all other content
    • Many performance improvements already made during the groundwork
    • once pref'ed on, it will allow SVG to benefit from more existing performance optimizations (layers) and future performance optimizations (off main thread compositing, DLBI)
    • will allow other web platform consistency/parity features such as z-index to be implemented in SVG
  • landing plan for display list based invalidation (DLBI) is to split landing into a few pieces
    • still risk of regressions with each piece, but more manageable
    • some extra work needed to land pieces separately
    • high cost of merging with other changes to the code
    • trying to land automated tests for bugs reported after the previous landing
    • first piece and second piece landed
  • pieces of off-main-thread animations landed / landing: bug 706179, bug 755084
    • starting off with animating just transforms and opacity in the layer system
    • still running style change handling on the main thread, just suppressing repainting (to be improved later, but tricky)
  • other notable patches landed:
    • bug 745148: Support content processes pushing layer transactions directly to off-main-thread compositor in parent process (for b2g, spread across gfx / dom / layout)

Media

DOM

WebAPI

Network

Identity
