In D? Almost none. It was manual memory management with GC 
enabled side-by-side. If you want to compare D GC with JVM GC, 
don't pretend you are comparing D with Java. Problem with D GC is 
that collection cycles can still hit sometimes even if there are 
almost zero garbage and it does not matter that nothing is 
actually collected - the very existence of context switch and 
collection cycle creates latency spike.
