Bad performance after opening any typescript or css file

[killerart]

After opening and typescript (react tsx) or css file, any actions become delayed by approximately 1 second like switching between buffers, switching to file tree, starting typing a command or opening/switching to a terminal. So any action just freezes nvim for an entire second.

I don't have any modifications to the code besides a few keymappings.

Neovim 8.3 M1 iMac

Started getting the issue after the "lazy" update

[ecosse3]

I think that's a bit of expected behaviour that UI will be frozen for 200-500ms because that's the time to load TypeScript Language Server tsserver. Could you please show the output of :Lazy profile, :Lazy debug after opening a tsx or css file?

Did you install LSP servers via Mason or manually via npm/yarn?

You can always try to opt-out from using them and use faster alternative like bun. I tried it but didn't have better results.

:Lazy profile after opening a tsx file:

  Startuptime: 112.57ms

  Based on the actual CPU time of the Neovim process till UIEnter.
  This is more accurate than `nvim --startuptime`.
    LazyStart 15.61ms
    LazyDone  61.02ms (+45.42ms)
    UIEnter   112.57ms (+51.55ms)

I understand that tsserver is loading for quite a while and it is expected to freeze a little on the first open, but it happens even after it's loaded on every window change, or just moving the cursor to nvim-tree and back to tsx file. The tsserver should already be loaded by that point

[killerart]

I've installed LSP servers via Mason

[killerart]

I also have LuaJIT version 5.4.4_1, if that would help

[killerart]

I downgraded EcoVim to release 2.4.2 and the performance is great

[killerart]

I don't know what the issue was, but I cleared ~/.local/nvim and ~/.cache/nvim and it got fixed.

[ecosse3]

I am happy that's resolved! I couldn't reproduce it as well and didn't think that could be a cache problem.
