ARM and Intel have different performance characteristics

I commented that I expected it to do well on x64 processors (Intel and AMD), but not so well on ARM processors. Let me reuse my benchmark where I simply sum up 524288 random integers are record how long it takes…

According to my tests, on the x64 processor, wyhash is five times faster than splitmix. When I switch to my ARM server, wyhash becomes 4 times slower.
