91103e1 is running on a different branch, so only the cache in its branch is used. For evaluating sccache's overall performance, please try again.

After this PR gets merged, all other branches can reuse the cache from the main branch.

Sccache will be slower than rust-cache when Cargo.lock nearly not changed.

Overall it looks a lot better than the last time I tried.

Looks like the gha cache API limit issue also affects the Test Docker job, I guess we can switch to registry cache instead in docker-build-push-action to avoid it.

✨ Merging, will switch to official version of the sccache-action when it's released. Thanks!
