[jakebailey]

Check time performance and baselines don't seem to look good, unfortunately.

[Andarist]

@jakebailey I've pushed out a change - there is something funky in its 2 baseline changes but for now, I'd like to just learn its perf characteristics. Would you mind re-running the perf test suite?

[jakebailey]

@typescript-bot perf test this

[typescript-bot]

Heya @jakebailey, I've started to run the perf test suite on this PR at e244365. You can monitor the build here.

Update: The results are in!

[typescript-bot]

@jakebailey
The results of the perf run you requested are in!

Here they are:
