Details

bug 1688788 (and partially bug 1687973) is blocked by performance regression because of moving atomization from helper thread to main thread.

The batch on-main-thread atomization needs to be optimized.
Possible places:

  • reduce the number of GC locks, by performing atomization as a batch operation, instead of atomizing one by one
  • perform some more preparation off main thread to reduce on-main-thread work
