Comment Interesting, but compiler settings aren't optimal (Score 4, Insightful) 57

Look here at the compiler settings. The x86 processors are somewhat hampered by non-optimal settings. For example the i3 5010U is set to -mtune=generic. In my experience, that's basically going to default to AMD K8 optimization with no AVX/AVX2 support. The better option would be using -mtune=native or better yet -march=native, which would detect the CPU and produce a more optimized binary.
