I have actually seen a few posts here and there of 'cargo check' being slow. I have also heard of complaints of rust-analyzer being slow, though rust-analyzer may be doing more than just 'cargo check'.

May not be indicative, not sure what crate the author was using.

cargo check can be slow but what I mean is relative to a full build. Large projects are going to be slow to build by virtue of being large.

That project had 'cargo check' take 15-20 minutes, though it might not have been indicative, the submitter posted an update about how it was fixed.

This may be a better example.

>cargo check with 1.82: 6m 19s

>cargo check with 1.81: 1m 22s

It may be difficult to fix.

>Triage notes (AFAIUI): #132625 is merged, but the compile time is not fully clawed back as #132625 is a compromise between (full) soundness and performance in favor of a full revert (full revert would bring back more soundness problems AFAICT)

Update: They fixed it, but another issue surfaced, possibly related, as I read the comments.
