### Share the Go related settings you have added/edited

Run `Preferences: Open Settings (JSON)` command to open your settings.json file.
Share all the settings with the `go.` or `["go"]` or `gopls` prefixes.

"go.useLanguageServer": true,
"go.toolsManagement.autoUpdate": true,



### Describe the bug
Code completion and popup hints are extremely slow. When I type functions to be called I can literally see the highlighting progress. See attached GIFs for a comparison.

### Screenshots or recordings

A single module:

Multi-root workspace with 5 Go Modules:

Thank you for filing this report. We know that the UX of working with multiple modules isn't great right now, so we're looking at an improved workflow--experimental workspace module support. For now, I either suggest opening one module at a time or trying out this experimental mode if it fits your needs.

Thank you @stamblerre for your explanation. I'll fall back to single-module for now. 👍🏻
