I ported a classic DeltaBlue benchmark to D, and for
allocations I use a mix of malloc/free (for structs with some
trailing inline arrays), and new for some other structs and

After running it, it felt kind of slow (I did not compare it to
any other language yet, so no idea if it is actually slower,
just feels slow), so I did some profiling (perf / hotspot
mostly), and noticed that substantial amount of time is spent
in gc (both allocation and collection). This is on Linux, and
benchmark indeed creates a lot of garbage, as I rerun and rerun
it in a loop.
care to share some numbers?
did you try the forking GC on Linux, too ?
