Need to do some perf analysis  on this one. dbaron will look into this over the next couple of weeks. Peterv has a patch that he's kept up to date and will attach that to the bug. It's not clear that the patch will change anything (leak wise), but it might have help performance and make the code more maintainable, GC stuff gets hidden behind the API etc.

* Two patches dbaron's review queue.
We're done fixing new leaks AFAWK, now we can concentrate on finding old leaks etc. Leaks are down to 3k or so, so not too much to go after in the normal case.
* After the two patches, we need to have specific test cases and look for leaks.

Agenda

  • status of patches in progress: All we've done in the past week is review peterv's and Igor's patches. We still need to land some of these (basically we are almost in the same spot as last week).

Status of Pending CC Code in Bugzilla

Later:

  • bug 381199: revisit cycle collector aging strategy

Dbaron will look at this over the next couple of weeks as well.

Performance requirements

Criteria for Performance Satisfactory:

  • Double the current GC time.

Next steps on leaks

We're done fixing new leaks AFAWK, now we can concentrate on finding old leaks etc. Leaks are down to 3k or so, so not too much to go after in the normal case.

Next steps on performance (pauses)

Next steps on performance (general degradation)
