If you need sub-microsecond latencies then the requirements can be summarized as "don't allocate, don't deallocate." Now the memory management technique is irrelevant, because the goal is to avoid memory management at all costs. Yes you'll need a memory pool design in whatever language. But most GC'd languages only collect at allocation sites, and so if you don't allocate you won't trigger a GC.
