I've found that when using the github.com/uudashr/gopkgs version of gopkgs, my CPU spikes for a long time and many on-save operations are extremely slow. If you look in your your Activity Monitor (on MacOS) or presumably Task Manager (on Windows if affected), you'll see gopkgs whirring away and not a lot happening in vscode.

I do have a pretty busy GOPATH (96 github.com subfolders etc.) but only open the top-level directory of the project I'm working on.

Since removing github.com/uudashr/gopkgs and replacing with github.com/tpng/gopkgs my IDE has come back to life but I keep getting prompted to install github.com/uudashr/gopkgs for the best experience. I can confirm that when I do heed the suggestion and re-install the uudashr version, my IDE grinds to a halt again.
