What was the performance relationship with respect to garbage
volume? was
it linear?
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.
