What did you do?

I removed the fmt import from this file.

package main

import (
	"flag"
	"fmt"
)

var testflag string

func main() {
	flag.StringVar(&testflag, "", "", "")

	fmt.Println("hi")
}

To isolate this issue, I have:

• updated go to 1.25
• disabled Windows Defender
• disabled all VS Code extensions except Go
• tried disabling VS Code integrated LSP

What did you see happen?

gopls took 5 seconds to reconcile this action and highlight the missing import. What I can deduce from the logs is that go list is taking 3.2420477s to complete. I'm unsure why and I have done my best to isolate it.

What did you expect to see?

Running this in WSL2, I get 200ms performance for this. This is a reasonable amount of time.

Are you sure you don't have something like antivirus that interferes with operations in windows but can't look at things inside wsl?

[wes-mil]

I have disabled antivirus. It doesn't appear to make a difference

[pobearm]

I also have similar problem, vscode open my workspace on windows 11 enterprise version, go 1.20.
Vscode show : Loading packages..., for 5 minutes. And when i reopen vscode, i will take 5 minutes again.
If loading packages failed, no code suggestions in vscode and cannot save file(vscode block me for something).
But on linux go 1.20, it work fine.
