Hello,

Thanks for creating this program, it has more features in comparison to rnix-lsp and the diagnostic messages are better as well IMO. However, I have to reside to using rnix-lsp never the less, due to performance issues when I edit all-packages.nix, in Neovim, using nvim-lspconfig. If I turn on completion using nvim-cmp, it becomes so slow it's impossible to edit a single line.

Due to my suspicion that this is an issue with one of these neovim plugins, I created a repository with minimal configuration that reproduces the experience:

What's frustrating, is that I can't seem to turn nil off when I edit large files such as all-packages.nix - this is more of a nvim-lspconfig issue I guess, which I have asked about here. In anycase, with rnix-lsp I don't experience this issue so that's what I am doing now.
