> It's often painfully slow to respond even in small project

I had that problem with NeoVim's Mason plugin that manages language servers, then I just cloned `elixir-ls` and made a super small script to update it daily from GitHub and recompile it. I use that in NeoVim instead and it works near-instantly. Give it a try.

I don't disagree that IDE support can look subpar but I'd also venture a guess that proper IDE support is very first-world problem. You won't find yourself working on projects with millions of lines in Elixir ever, and thus not having e.g. full-blown IDE refactoring has never been a problem for me or any other Elixir dev I know.

All that being said, literally nothing I have ever saw was able to beat Golang's and OCaml's language servers. They just work and are amazingly fast to boot. It's simply a joy coding in those languages with their LS. Rust is trailing closely behind but it's also a fact that its LS is objectively slower -- still, they seem to have made a lot of strides on that front lately and it's much better compared to even one year ago.
