Incremental Garbage Collection

Feature Status Release Target Dev Lead QA Lead Status
Incremental GC Landed Firefox 13 Bill McCloskey Ioana Budnar Signed off on Aurora

Summary

  • Garbage collection time is divided into short increments. Overall, the same amount of time is spent doing garbage colletion, but each individual pause is shorter.

References

Use Cases

  • Use Firefox with incremental garbage collection enabled. When IGC is enabled, dynamic content on the web should have more tolerable pauses (possibly go from noticeable pauses to ones the user cannot notice).
  • Disable incremental garbage collection.

Test Cases

  • The test cases for this feature can be viewed here.

Important Bugs

  • 641025 - Incremental GC
  • 734946 - Disable incremental GC for Firefox 13
  • 728692 - Javascript becomes slow after Incremental GC gets disabled
  • 735944 - about:support says "incremental gc: 1" when javascript.options.mem.gc_incremental is disabled
  • 728686 - JS_NewPropertyIterator disables IGC
  • 730853 - If incremental GC or compartment GC runs all the time, CC never runs
  • 752098 - Crashes on MemBench with incremental GC enabled
  • 735099 - Re-enable incremental GC on desktop platforms

Not Tested
