Cycles and memory resources usage

Assuming all data fit into the L1 cache, each iteration of the binary loop takes 3.50 cycles. At this rate:

47% of peak load performance is reached (45.71 out of 96.00 bytes loaded per cycle (GB/s @ 1GHz))
38% of peak store performance is reached (18.29 out of 48.00 bytes stored per cycle (GB/s @ 1GHz))

Front-end bottlenecks

Found no such bottlenecks.

ASM code

In the binary file, the address of the loop is: 41c580
