codeium.nvim makes NeoVim laggy and unresponsive

[MuhammadSawalhy]

I noticed that my NeoVim is laggy during typing which was annoying and slows down me affecting my productivity. After some exploration by disabled and re-enabling some installed plugins, I discovered that codeium.nvim is the source of this lagging.

Here's a screen recording shows exactly how it feels.

Same here. When using copilot for instance the performance is not affected. Maybe this is related to cmp?

@MuhammadSawalhy it appears you're enabling/disabling codeium.vim in your config; not codeium.nvim.

Not sure if you meant to open the issue here but you may want to open it in Exafunction/codeium.vim instead.

@cleong14 Oh, thanks I didn't notice that.

I remember that I use codeium.vim because I need the virtual text preview of the completion instead of filling the completion list of nvim-cmp with many AI-generated suggestions.

There exists already an issue asking to implement the virtual text preview feature and this comment https://github.com/Exafunction/codeium.nvim/issues/14#issuecomment-1411322109 from the maintainer says:

I plan to do this eventually, but given that codeium.vim already does this, it's pretty low on my priority list.

Now I should choose between having this feature but make the performance bad or using codeium.nvim and losing this feature!

Anyway, this issue should be in codeium.vim not here, I'll open an issue there.
