I've been using golangci-lint for years, it's okay but it's slow even with a cache, as soon as you have good amount of lints enabled your ci can suddendly take minutes.

That's not the fault of golangci-lint, it's just the concept of bringing together a bunch of different linters and keeping it fast is impossible. And the configuration is a bit wild too, because every linter obviously has their own decisions on how it wants to be configured.

Ruff can lint in seconds or even sub second.
