Vladan on PTO April 2-18, Avi Halachmi (:avih) substituting

Asus Transfomer T100 laptop/tablet initiative:

  • Focus on providing the best user experience (UX feel, features, performance) on lowest common denominator hardware
    • Try to become the best browser on this specific hardware
    • Firefox will be even better on higher spec stuff
  • Our test machines should be different from our development machines (similar to Android development)
  • Procure it as needed for your projects: http://www.newegg.com/Product/Product.aspx?Item=9SIA2NR1AU2763
  • Why this particular device:
    • Popular: according to Amazon.com, it's been one of top sellers in the "Laptop Computers" category for months
    • Both tablet & laptop formats
    • Cheap + low-end (Atom CPU, integrated graphics, SSD+HDD)

Profiler enhancements:

  • bug 963158: Profiler shouldn't sample sleeping threads multiple times
  • bug 987297: Improve memory usage of profiler by packing ProfileEntry structs together better
  • bug 962262: Use external structure padding to save ~30% of circular buffer space
  • bug 986160: Create unit tests for the Gecko Profiler
  • bug 967619: Talos Profiling has hit some snags, likely Talos profiling on Windows will not be initially supported
  • bug 758697: Working on improving profiler support for B2G

Most common sources of main-thread I/O, according to Telemetry:

Miscellaneous fixes:

  • bug 987101: Switch the CrashMonitor to native OS.File.read() for better performance
