I feel like rust analyzer is slow

Like the title says

I run rust analyzer on my vim (not nvim) setup and it just takes forever to load. Mind that I’m on a fairly powerful machine.

Also, the fact that I have to save the document to get error checking is driving me crazy.

I’m mainly comparing this with Zig’s lsp which I rocked for several months with the same setup and would update immediately every time.

Does anyone else have this problem? any recommendations?
