Thanks for the issue but it's not actionable without the performance information. Do you still have it?

once any python project opene, CPU usage %7+ (section: Process Info )

[rchiodo]

That would be expected. The python extension is looking for interpreters on startup.

That also would not have generated a 'slow extension' notification for the Python extension or the Pylance extension. Usually there's a notification that says that and it copies the performance data to the clipboard.

[lackwb]

I am also experiencing the same issue. Even after closing all the files, Pylance is still showing a "consistently" high CPU usage. Today, I updated everything(VSCode v1.77.1, Pylance v2023.4.10) and the issue persists both before and after the update.

[rchiodo]

@lackwb can you get the command line arguments for that process? It should be really quick, but perhaps it's looking for the config in the wrong spot.

[lackwb]

Do you mean this?

Yeah that was it. Your problem is a dupe of #4218. It would be better if you followed that issue.

I will. Thank you.
