Caching unsatisactory

[ennioVisco]

We are testing bun as an alternative to pnpm, but the caching is quite unsatisfactory in a monorepo setting.

In our case, the installation time takes ~37 secs (~2k packages), which is super nice, but we don't seem to be able to reduce this time in subsequent tasks in any way.
Any ideas how to reduce the time in chained tasks (Github Actions) of a workflow?

We don't cache dependencies, only bun versions. Maybe you can try #14 (comment)

I tried, but it seems to take more time.
Is there any reason why dependencies are not cached?

I think we've come to conclusion that it takes even longer than reinstalling. If I can ask, what was your original time with pnpm?

When the cache is present, 11 secs, but it could be related to the fact that in pnpm I can limit the packages to install, while in bun I just have to install them all.

One thing that I still don't get is why do I have to re-install, Isn't there a way to say, "Just restore the state from this directory"?

I think one of the reasons why it is taking longer is because it is installing and re-linking everything even if it doesn't need to.
This bug should be fixed in 1.1.11, but the caching of #14 (comment) seems to not skip the re-installation correctly, perhaps some files have to be added to the cache that are currently not?
