A 16GB heap that's mostly live objects will take tens of seconds per round The situation you describe, as you describe it, is (no longer - was it ever?) a pathological case. I run stuff with 12-20GB active objects and a few dozen http hits a second and the only times I get a latency over 100ms is when I reload/refresh some data from disk (1.5GB of gob), then it goes to 150-250ms typically.
