Caching makes the setup step extremely slow

I experienced the same issue on ubuntu-latest and macos-latest images.

In https://github.com/pangeo-forge/pangeo-forge-recipes/pull/231#issuecomment-966623474 we have also found that caching (following the procedure recommended in the docs) does not speed up our builds at all.

Does anyone have evidence of a working cache setup that makes this action run faster?

I recently found how to cache the installed environment instead of caching the downloaded packages, maybe is useful: https://dev.to/epassaro/caching-anaconda-environments-in-github-actions-5hde
