You seem to have a number of particularly expensive packages, notably golang.org/x/text, open in your workspace. Have you opened your entire GOPATH as your workspace folder? That will definitely lead to very high memory usage. We'd like to be more efficient, but for now you will be much better off opening just the project you're working on.

Hi @heschik, I just have one project and all the packages that I have installed is what i'm using.
Can I just disable the execution?

Please make sure that the folder you've opened as your workspace folder in VSCode contains only code you've written. If you still see high memory usage, please upload a gopls log following https://github.com/golang/vscode-go/blob/master/docs/troubleshooting.md#collect-gopls-information?
