fileWatcher keeps consuming CPU at 200%+

[u3u]

Type: Performance Issue

I don't know under what circumstances this problem will occur. It will continue to occupy the CPU forever and will not stop unless I exit VSCode. I have already excluded unnecessary directories in the settings.

  "files.watcherExclude": {
    "**/.git": true,

[u3u]

It is still ongoing 😰

[bpasero]

Does it change if you set typescript.tsserver.experimental.useVsCodeWatcher to false?

[u3u]

Is there this option?! Let me try! These are my current tsserver settings:

{
  "typescript.tsserver.experimental.enableProjectDiagnostics": false,
  "typescript.tsserver.maxTsServerMemory": 9216,
}

[bpasero]

Yes, it is a setting in VSCode itself!

[vs-code-engineering]

This issue has been closed automatically because it needs more information and has not had recent activity. See also our issue reporting guidelines.

Happy Coding!

[u3u]

Okay, After disabling typescript.tsserver.experimental.useVsCodeWatcher, it has indeed not occurred again during this period.

[bpasero]

Is the repository where this reproduces something I can try on my machine, i.e. open source?

[u3u]

Sorry, this project is a company project and cannot be open-sourced. It is a large Monorepo project that includes several websites, public components, public utility packages, etc. I don't know the total number of files in this project, but most of them are .ts and .tsx files. There should be at least tens of thousands of .ts files 😓.

[bpasero]

ℹ I would appreciate if people impacted here could try out our latest insiders build (commit c4efe1dc9eec4914f3076b2d954fe4fe174a5820). It includes a change to reduce the pressure of file watching from the TypeScript extension.

Steps:

• download insiders from https://code.visualstudio.com/insiders/
• configure typescript.tsserver.experimental.useVsCodeWatcher to the default value of true
• please make sure your files.watcherExclude setting does not include **/node_modules/*/**
• perform your workload that was showing issues

Happy to hear back how it goes 🙏

[fabroce]

I had this problem and since 1.94 no more CPU stress.
Thanks.
