I don't know this field, perhaps my bar is low because of Python lol, but Go's GC has very short GC pauses. So short that it makes non-GC'd usecases less attractive imo.

My big issue with Go's GC, or GC's in general, is consistency. Go's GC can still be variable in pause time iirc. But it's been ~3 years since i've worked in it - so maybe my memory is wrong :)

From what I understand Python uses reference counting, which is a type of garbage collection that allows you to have deterministic performance, almost no "pauses" but at the cost of performance.

About the consistency, I think that's not a GC problem in general. For example, Java's ZGC has constant pause times: https://malloc.se/blog/zgc-jdk16.
