I see you have removed the asm guard I have shown you.
I suggest you to benchmark it against another normal D function. Keep in mind
that asm blocks kill inlining.
Also try to perform a load-load-load processing-processing-processing
store-store-store instead a load-processing-store load-processing-store
load-processing-store, because this often helps the pipelining of the processor
(expecially when you use SSE/AVX registers).
