If I read your benchmark graphs right, they claimed that allocating 16 kilobytes takes over 10^^6 usecs, with both mallocs. Doesn't that mean over a second, 16 kilobytes? Can't be! Are you confusing usecs with nsecs?
The benchmark doesn't allocate any data; it's just copying data. Each benchmark is run 10,000,000 times to smooth out some of the entropy in the results: https://github.com/JinShil/memcpyD/blob/2e0d3c33ea876a25a04358a3ae505b2eba9f99cb/memcpyd.d#L78 The usecs in the graph is the time it takes to run the benchmark 10,000,000 times.
