Performance issues VSC extension on version newer than 1.31.1

[RuizuKun-Dev]

I'm having issues with versions newer than 1.31.1, meaning version 1.31.1 has no issue but 1.32.0 and above do

Whenever i type something it doesn't update properly and sometimes even crashes

Please provide some reproduction steps since unforunately there is not much I can do to diagnose this otherwise

that's really tough because for me it always happens no matter what i do here's a video

Code_25TRL0kPlg.mp4

I'm on version 1.32.3

I keep getting this too whenever i have to reload Luau-LSP and when opening VS Code

I plan on taking a deeper look at LSP performance issues. Can you generate a trace.json file and send it to me when you experience slowdowns? You will need to use a nightly build, but the steps are:

1. Download the latest nightly from https://github.com/JohnnyMorganz/luau-lsp/actions/workflows/nightly.yml for your platform. It will contain an archive for your platform. Download and extract, and you'll find a .vsix file inside. Install this into VSCode
2. Launch VSCode and enable the FFlag DebugLuauTimeTracing
3. Reload your window
4. Perform your work as normal
5. Run Luau: Flush Time Tracing Events to tracing.json command to write out a JSON file

This JSON file can be loaded into a visualiser such as chrome://tracing or Perfetto.

This will help to pinpoint the performance issues

yep, i'll do that for you when i get the chance
