Describe your issue

If I enable the tailwindcss-intellisense extension and launch VS Code in a project directory that does not have any TailwindCSS code (AFAIK) the extension spawns a rg process that uses 1000%+ CPU.

This project is an private one that I use to manage container apps on my workstation. It has a data directory that container applications like home assistant, paperless, gitea etc use as volume mounts.

Some of these projects do have .ts and .js files in this directory so maybe it is choking on watching all of those files? Maybe the extension should check for a tailwind config and only spawn the rg process if it knows that TailwindCSS is being used in the project root?

Looks like Dev Container's had a similar issue that they fixed / worked around: https://github.com/microsoft/vscode-remote-release/issues/9738

It's not open source (that I can see) so I don't know exactly what they did to fix it but one of the comments gave me potential ideas to go on. I'll see what I can come up with.

Thanks for reporting this!

[thecrypticace]

Okay so a couple of questions:

• Are you using PNPM for any of those projects?
• If you take that manual rg command from ps and run it yourself in the same working directory without the --follow flag does it complete quickly?
• Do you know what kind of mounts you are using in Docker? Are they actual volume mounts, bindfs, or something else?
• What storage driver are the mounts using?

You're on an NVMe SSD so I doubt drive speed is not even remotely in play here. I wonder if Docker is doing something weird with those directories that causes directory listing and/or other file operations to slow down.

I think I've found something similar in my project. It's a Python data project that as part of normal operation will install tens or hundreds of node projects. There's no tailwind install or config in the project root though, is there a sensible way I can disable it? I have the plugin installed for other projects I work on 😃

i think i have a similar problem. I noticed when my laptop suddenly started crashing. When i looked into my processes: I'm using v0.0.24 with neovim (btw). I just opened a index.vue file in an empty folder.
