  • No longer use symbols for asyncId & triggerAsyncId. This borrows from the seemingly abandoned PR at process: improve nextTick performance #25461 by @mscdex. (Credit provided in the commit but happy to also remove this portion of the code.)
  • No longer check process.exiting on each tick add.
  • Cleaner emitDestroy with try/finally.
  • No longer use Reflect.apply since it's slower.

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • tests and/or benchmarks are included
  • documentation is changed or added

FWIW my PR for improving nextTick performance isn't abandoned, I just haven't had time to revisit it yet.

Also, this PR is now exposing asyncId and triggerAsyncId on the object passed to the hook(s) more directly. I think we should be hiding those sorts of things from hooks, as I believe that may be why Symbols were used in the first place.
