Caching

[InAnYan]

This may be a niche issue, but I think it's important to address:

Many programs use caches to improve performance by reducing the need to recalculate information. LSP servers can benefit from this approach as well.

However, if you introduce a caching mechanism, please ensure that caches are persisted to disk. I have extensive experience with Rust, and its LSP server never stores intermediate results or compilation data between sessions. Every time I reopen a project (after working one day, then returning the next), I have to wait about 5 minutes for all dependencies to be analyzed and compiled again.

This is worth keeping in mind. You can see how popular this feature request is in this issue: rust-lang/rust-analyzer#4712

Actually, I don't think people edit giant bib files...

Though we have people who have libraries with over 10k entries

This is quite similar to #46? Thus, my comment at #46 (comment) stays the same.
