- jchw 8y agoxxHash is still very fast. In fact, I am sure that some implementations of xxHash are faster than that. In fact, after Googling it, I can see that xxHash64 is quoted as having 3.1 bytes per cycle, which is not bad. xxHash is also very simple, and can be written easily in high or low level languages, which I like. Someone even implemented it in C++ templates I believe. I don't know how Meow Hash is but I imagine the default implementation heavily exploits AMD64 CPUs and based on the article probably makes use of AES acceleration. Basically, if you do this, at least be sure you're not bottlenecked on I/O already :)
