Using more cores makes golangci-lint run slower (?)

[njern]

Welcome

• Yes, I'm using a binary release within 2 latest releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've read the typecheck section of the FAQ.
• Yes, I've tried with the standalone linter if available (e.g., gocritic, go vet, etc.).
• I agree to follow this project's Code of Conduct

Description of the problem

I noticed that both when running a "clean" and a "cached" golangci-lint, setting the core limit lower (with the -j option) seems to improve performance, to a point. It is especially noticeable for cached linting runs.

I first noticed this in our own internal repository but I have reproduced it using the golangci-lint repo.

All these commands were run on a Macbook Pro M4 Max (where golangci-lint defaults to using 16 cores).

	cache	time
default	no cache	32.555855417s
-j 4	no cache	29.854271375s
default	cache	2.155626167s
-j 4	cache	1.69703725s

golangci-lint run -v (after golangci-lint cache clean)

Hey, thank you for opening your first Issue ! 🙂 If you would like to contribute we have a guide for contributors.

Hello,

In some cases using all the cores doesn't provide the best performance, this is not unexpected because the CPU is one of the limits of a system when using parallel processes.

I think it's because we are hitting other limitations than the CPU related to concurrency access (memory, FS, other processes, etc.).

But as you can see the "best" value for the CPU depends on the system, so it's not possible to do something smart on this topic.

	cache	time
default	no cache	23.078625285s
-j 4	no cache	39.784760618s
-j 6	no cache	28.895793532s
default	cache	1.026388844s
-j 4	cache	1.047746156s
-j 6	cache	967.3105ms

I also have 16 cores, but on Linux amd64.

Also, the cache is not a global thing for golangci-lint, I mean it's not "all or nothing" because the cache is by package, and the invalidation of cache is by package too.
Due to that, it's not possible, from the POV of golangci-lint, to really know if there is a cache, and these benchmarks should be evaluated carefully.
