Hello! Wondering if you would be open to making some perf improvements that I identified?
Background:
I've been trying to improve performance on a test suite using Storybook test runner on a Github Actions based CI.
What I did:
I ran the test suite locally profiling with Clinic flame.
react-docgen-typescripthad some very hot blocks in the flame graph that I was able to cool down substantially by caching the results of some functions.For reference, here's the initial run showing
trimFileName.jsas the hottest block in the entire profile. (Updated image, I put the wrong one at first...)Results:
My 33 test suites containing 63 tests in total dropped from ~26 seconds to ~14 seconds.
What I don't know:
If the cache keys I used are safe (could there be name collisions?). If you're interested in this kind of micro optimization for this repo.
