  • AI: justin
  • AI: ben
    • ben to build current mini's (has access)
  • AI: justin
    • justin to stock up on minis - ordering 50, only for perf
    • IT to build and image, and if possible, get on tree
  • AI: Alice
    • get in each OS ready to be imaged for new minis


  • Moz2 mini farm implementation
    • number of machines -
    • 18 machines for trunk & branch
    • plan to roll them out
    • IT to take images and roll them out.
  • bhearsum is going to be working primarily in Build for the next 1-2 months.
    • Will still be supporting the existing Talos machines
    • Working on Try server Talos, Vista slaves, baselines is on the back burner for now.

  • Talk about the happenings on the tree wrt bug 400045
    • Ben/Robcee to look at numbers
    • still not resolved, justin to follow up

    • Agreed goals:
      • stable production talos for branch trunk (4 platforms) on tree
      • perf enabled try server
      • stand alone talos box
      • baselines for historical numbers
      • graph server improvements (perhaps seneca)
      • investigate (rock) performance solutions for mobile
      • Bring up new tinderboxen to run leak and mochi tests on debug builds.

Gecko: Perf discussion

  • dtrace status
    • main patch is in, followup patch for Leopard exists bug 401806
    • need to figure out how we're going to ship this (is it enough to build with the header file on 10.4, or do we actually need 10.5's compile-time linker?)
  • Followups
    • sessionStore is really slow -- bug 398807 -- checked in, remaining issues marked blocking-, does this need to be tracked any more?
      • waiting for native json serializer to land
    • force cycle collection in between page load in talos (bug # needed)
      • TODO: vlad -- figure out what's going on there (with jonas)
  • Firefox front-end perf
    • sayer to put list of tasks on wiki
    • focus on measurements on tabbrowser reduction
    • dolske will do some profiling work
  • On radar
    • Stuart's page-out/page-in tests?
    • Theme optimization
    • roc's scrollbar issues
    • startup performance (fastload perf, loading libXUL and other files, etc.) (unowned)
    • more work to speed up onSecurityChange, but further work will require SSL work and reducing the number of notifications
    • others?
