There was a problem hiding this comment.
This should have been memoized anyway, I don't think that's what caused the regression though but let's see.

What?
Follow-up to #40054, which appears to have had minimal effect on performance.
This PR attempts to optimize
getClientIdsOfDescendantsusing memoization.Why?
#39985 seems to have reduced performance a bit, and #40054 doesn't seem to have done much to counteract that.
How?
This PR wraps
getClientIdsOfDescendantsincreateSelector, which should help memoize the selector.getClientIdsWithDescendantswas already usingcreateSelector, so I think this makes sense.Testing Instructions
Check the "Performances Tests" in the PR checks to get an initial impression. If it looks promising, I guess try merging this and monitor the "Block Select" metric at http://codehealth.vercel.app/ over the next several commits in
trunk.
