Firefox 3.1 Update

Places Fsync-reduction Changes

• Goal: reduce fsyncs by writing to the disk less often, reducing hangs/freezes/sluggishness while browsing (especially hurting mobile, usb and some linux).
• Approach: keep non-critical history data in temporary tables, periodically flushing to permanent tables in the background.
• Problems
  • Ts (bug 459197)
    • Initial landing caused a regression of ~3% on linux and ~4% on windows (data)
    • With fixes, still seeing regressions: (data)
      • Linux is at 1-2% (30-40ms)
      • Windows XP is at ~2% (~20ms)
      • Windows Vista is at 1.2-2.5% (7-15ms) depending on which boxes you look at
  • Tp (bug 459235)
    • Initial landing caused a regression of about ~3% on OS X; possible regression on windows (data)
    • With fixes, possibly only small regression on mac, and ~1% win on linux (data)
• Solutions
  • This work is not going to make 3.1; push to next release and make no improvements in this area
  • slip beta 2 until we get the performance issues fixed with other performance improvements
  • let this work land and accept the fact that we’ll take some small hits in some performance benchmarks
