It's the fastest hash, and it's pretty good. Every intel 64 bit CPU should have it, and the new arm's also. See https://github.com/rurban/smhasher#smhasher
You just need to probe for it. Best try the one in -lz at first, and if it's the HW assisted one, not the SW, use that. Otherwise the one at https://github.com/rurban/smhasher/blob/master/crc32_hw.c
