x/tools/gopls: high memory consumption #47855
Description
What version of Go are you using (go version)?
$ go version go version go1.17 linux/amd64
Does this issue reproduce with the latest release?
Yes. I have the latest versions of gopls and go.
What operating system and processor architecture are you using (go env)?
go env Output

What did you do?
Opened cockroachDB repository in vim(same thing with neovim) with vim-go plugin and gopls enabled.
I've removed everything but vim-go and gopls from the .vimrc and disabled all other plugins. But the result is the same.
What did you expect to see?
Normal memory consumption. For example, Jetbrains Goland uses ~2GB when this project is open
What did you see instead?
gopls consumes about 9GB of memory, sometimes more than 14GB.
