I think it's well known that accessing a windows filesystem from WSL is quite slow, see "Performance across OS file systems":
https://learn.microsoft.com/en-us/windows/wsl/compare-versions#comparing-features

I don't think there's much for the Go project to do?

An idea, how about tcp communication after starting go list?
Another idea is that go list seems to be looking for dep, is there a way to read std once to get the dep of all the libraries?

cmd/api: Increase test parallelism
742f8e0 
In wsl2, accessing the Windows file system from WSL is very slow, and the final test execution can be longer than 10 minutes if the degree of parallelism is low.
By adding parallelism to make io start faster, the test time in wsl2 was reduced from 700+s to 280+s.

Fixes golang#65670
