> GC pauses: very slow (until Go anyway) If by "slow" you mean "high latency", then this isn't true. Plenty of GC algorithms provide guaranteed sub-millisecond

  It wasn't the norm until Go focused on it though, and "sub milliseconds" is not a high bar. Malloc is much much faster than that.

Malloc is much much faster than that. Malloc is not guaranteed to return in that time frame. The sub-millisecond latency of these GCs is a real-time guarantee.

        It doesn't though, which is why malloc is rarely used in embedded and realtime systems.
