[Feature Request] [Contributions Welcome] Performance benchmarks

[gvergnaud]

We should add some tooling to easily compare how changes affect type-checking performance

[ecyrbe]

Yes, automating this will require using tsc compiler to :

• no emit : just typechecking
• emit : measure impact on real builds
• maybe also check ts language server timings

I'm not too familiar with ts language server. first two should not pose any challenge

This looks very interesting https://github.com/arktypeio/arktype/blob/d90ca63/dev/test/operator.bench.ts

I am working on a library that may be helpful https://github.com/webNeat/ts-perf

it's still in beta as I am still experimenting different approaches to it.

My goal is to have a command line that can do the following

$ ts-perf tests/**/*.bench.ts

tests/foo.bench.ts  124ms
tests/bar.bench.ts   241ms
...

Arktype now has a benchmark tool. This can be useful for tests and benchmarks
