Vectorization

Your function is not vectorized. Only 55% of vector register length is used (average across all VPU instructions). By vectorizing your function, you can lower the cost of an iteration from 6.38 to 5.09 cycles (1.25x speedup).

Details

All VPU instructions are used in scalar version (process only one data element in vector registers). Since your execution units are vector units, only a vectorized function can use their full power.

Workaround

Try another compiler or update/tune your current one
Make array accesses unit-stride:
- If your function streams arrays of structures (AoS), try to use structures of arrays instead (SoA): for(i) a[i].x = b[i].x; (slow, non stride 1) => for(i) a.x[i] = b.x[i]; (fast, stride 1)
