I was wrong in my initial thoughts on the Go GC design. Apparently they improved it in the last years a bit. Still not state of art by far.

Esp. compaction is their latest "improvement", just implemented backwards, in the sweep phase. Now a moving collector is already compacting, no need to optimize for it to detect it in the sweep phase when the copying GC already puts them together.

No buzzwords, sorry. Simple technical concepts the Go people still don't get. Compaction is always needed, because that's the biggest run-time win in all environments. Cache misses.
