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.
