  • bug 1300411 - user reports excessive load spinning when switching tabs with e10s in 48.0.2 release
    • Posted a number of GC logs from a user that I'm in touch with over e-mail. In at least one, the user was OOM'ing.
    • Learning how to use analysis.telemetry.mozilla.org
      • Took a snapshot of pings sent in on September 23rd, and filtered down to clients that should have e10s enabled by default
      • Of these clients, a little over a quarter of them have seen at least one spinner of any length. We'll call these the "spinning clients"
      • Of the spinning clients:
        • ~82% of them saw a spinner of 2s or less ("low" bucket)
        • ~16% of them saw a spinner between 2s and 5s ("mid" bucket)
        • ~16% of them saw a spinner greater than 5s in length ("high" bucket)
      • Note that there is, of course, overlap between the clients in those buckets
        • ~2% of the spinning clients saw spinners in both the "mid" and "high" buckets
        • ~6% of the spinning clients saw spinners in both the "low" and "high" buckets
        • ~7% of the spinning clients saw spinners in both the "low" and "mid" buckets.
    • I think the only way we're going to grind these numbers down is by knowing exactly what the content process is doing so we can prioritize
    • Getting ramped up on bug 1303077
  • bug 1241459 - [e10s] A crashed background tab does not give option to submit
    • Have a behaviour spec, and a mostly complete plan on how to proceed
    • If a content process associated with any foreground tab crashes, same as current behaviour
    • If a content process associated with **only** background tabs crashes, show about:tabcrashed for the first of that set that the user selects, and the rest restore on demand.
    • If the user opts in to always sending backlogged crash reports, then if only background tabs crash, then all background tabs go into restore on demand state.

Helped out :mconley with some analysis stuff. We have a fairly good understanding of how many people are effected, but not how badly those people are effected. For instance: we know how many people are seeing spinners of various lengths... but how frequently are they seeing them?

Beta Release

felipe

  • bug 1304164 - Disable russian users from e10s
  • bug 1301131 - Disable e10s if the user sees the big tab spinner too much

aklotz

  • bug 1304449 - Rework MSAA child id generation for e10s - Main bug that fixes all the perf and stability issues - Still 2 patches needing review
  • Re-enabled tests that were disabled when a11y+e10s first landed (these are ones that were also failing on non-e10s mode)
  • Starting to look into Windows XP support

shell

  • CPOW disabling - investigating timing and extent of what that is
  • curious if spinner disabling bug will work for add-ons experiment as well.
    • are we concerned about it beyond e10s populations

Roundtable

  • tracking-e10s is no more
