What did you do?

Using Vscode and working with a project that has around 18000 lines of code. Some packages have around 8k lines.
Editing the go files and saving them.

What did you expect to see?

The file getting saved, autocompletion and linting working.

What did you see instead?

Whenever I save or edit the file the editor gets laggy and saving hangs for a while, sometimes up a minute with the message ''Getting code actions" , during that time autocompletion and linting does not work. Sometimes it helps to edit the file again and save again.
