Description
Just migrated our monorepo to bazel 8.x with bzlmod and tried to switch repo to use proto rules instead of pre-compiled go packages and for this reason tried to setup gopackagesdriver with vscode. The problem is that it works a bit slow and I wonder where this is issue with the bazel configuration or there is some bottleneck in the build process. Here are the environment details and I would be happy if you share some performance details or guideline how performance to be improved.

Contributor guide
Research direction
Start with the gopls log entries for go/pkg/cqrs/repository_test.go and the reported Bazel 8.3.1, bzlmod, proto rules, and gopackagesdriver setup. Reproduce the repeated 9–10 second go/packages.Load calls and determine whether the delay is in the Bazel configuration or build process; document the bottleneck and measurable performance guidance as done.
