Hi, Currently the xxhash package doesn't include the dispatch code in order to use SIMD, while it probably should on supported architectures (x86 & x64). This is done by setting adding DISPATCH=1 to the build env: https://github.com/Cyan4973/xxHash#build-modifiers My apologies if this isn't the proper way of reporting such a request
Also maybe CPU_FLAGS_X86 could be used instead to set XXH_VECTOR.
