Thanks for the report, and the details.

Gopls generally uses a lot of memory; this is something we know about and eventually want to mitigate. Memory scales approximately with the amount of code in the workspace. 2.9 GB is on the high side for 3670 go files, but not unheard of.

Could you please share your gopls version?

It’s the latest version. I’ve just updated it yesterday.

Closing this as a dupe of golang/go#47855. We hope to improve gopls' memory usage in Q12022.
