What did you do?

I use windows to develop go programs, recently found that my computer is getting slower and slower, when I open vscode, I don't run go run main.go, I just write go code in vscode, when I save the go file, my computer's cpu will suddenly rise to 100%, I don't know what's going on, I can only see that go.exe occupies a very high cpu,

What did you see happen?

when I save the go file, my computer's cpu will suddenly rise to 100%,as shown below

I wonder why: my computer's CPU spikes to 100% when I don't start the go run main.go program, just writing a static go file

What did you expect to see?

I wish I was writing a go file on window, the cpu wouldn't go up to 100%

Hi, I would love to get to the bottom of this, but we need more information, which may take a bit of back and forth. In general, the go commands run by VS Code or gopls should be short-lived, and should not be invoked on every save.

Those go commands could be started by gopls to list the workspace. Or they could perhaps be started either directly or indirectly by VS Code. Can you share the command line arguments or parent processes of those go commands, perhaps by using process explorer (https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer)
Sorry if that's not the best way -- I'm not a regular windows user.

Does this reproduce with just a simple workspace folder with, for example, just a main.go file?
