Remove cache for citool by Kobzol · Pull Request #143041 · rust-lang/rust (original) (raw)

I'm not sure why, but after the citool cache is loaded, compiling just build_helper and citool takes ~30s, which is very slow. Combined with the fact that just loading the cache takes ~15s, and we have to run a hacky workflow on master, which results in benign failures, I don't think it's worth it to use the cache here anymore.

A fresh build, now that we don't run citool tests on PR CI, takes just ~35-40s, so it's actually faster now not to cache. The trade-offs change quite often :)
