    • Roughly 3 person-months of work (!)
    • Already known regressions:

    • Temporary 5-15% JS perf regressions (15% on Talos; 5% in SunSpider harness)
    • So far, it's hard to tell if it's having an effect on crash rate--need to adjust for ADUs

Stability Report

  • ADUs still pretty low on the trunk - 40K but should see that increase Mon/Tues.
  • Since the ADUs are pretty low, we don't have many standout crashes.
  • Top browser crash list for yesterday - https://crash-analysis.mozilla.com/chofmann/20110530/top-7.0a1.html
  • Bug 648022 - Was fixed on 5.0 and backout was put on 6.0a2. Until we figure out the real fix, we will continue to see this signature on the trunk.
