Agenda

• cnn.com thread (dougt/jpr)
  • interruptible upload
    • + Easy to implement
    • - Will cause more checkerboarding
  • SurfaceTexture async upload (snorp)
    • snorp is working on flash again
  • gralloc async upload
    • Unclear what this means
  • async p-layers update
    • + Should provide a big performance improvement, is really wanted long term everywhere.
    • - Complex
    • Should we start it now?
      • We don't have enough resources. We need to investigate test failures and performance problems first.
    • Checkpoint next Monday.
  • Jank vs Checkerboarding? (joe)
    • Numbers from Kats: http://pastebin.mozilla.org/1481684
    • If it's ok to drop below 60 fps, we could checkerboard less.
    • Determined: We will probably need to do incremental upload
  • other things
    • skia profiling -> george to provide info
      • Gradients are about 30% faster than Cairo.
      • Blitting is about the same as Cairo.
      • Line drawing is about 50% slower than Cairo/Pixman.
      • Can we move the Skia gradient code into pixman? Chris Jones has mentioned it.
        • Jeff says that it's hard. People have tried in the past, and failed.
