  • Overall rate: 2.17 (browser), 0.44/0.99 (plugin crash/hang), target: <1.5; 0.07/0.14
  • bug 1156800 is top hang, just landed on m-a
  • browser crashes look on decent path, plugin still very bad


  • Overall rate: 1.55, target: <1.4
  • bug 1127270 (shutdownhang, layers::CompositorParent::ShutDown) is 3.5% in 38.0b8
  • bug 1116812 (probably-TDRs) is 3.3%
    • unsure if disabling DXVA would really make a big impact, having data would be good.

  • Issues with 38.0b8 crash data! Even more fallout from building out of m-r, see bug 1159993

Performance (Thu)

Aurora / Dev Edition




  • [otilia] after next merge we'll be building 38.0.5 from release - are there chances to hit issues like we did with 38.0 last beta builds? Based on this last experience I believe we won't as there are some lessons learned and Sylvestre did a great job in writing the blog post with the issues encountered, but just wanted to make sure everyone is on the same page with next builds.
    • we will have issues! We usually have beta version of X.YbA schema, here, with X.Y.ZbA
    • Any plans to build from another branch, other than release?
      • esr
  • Note that we need to sign off 4 builds next week - 38.0 RC, 31 ESR, 38 ESR, 38.0.5 beta
