    Meow Hash v0.2 will be arriving shortly. It is now the fastest hash on anything over 32 bytes, so for data hashing you can now pretty much just fire and forget:pic.twitter.com/EHTfv239jA

        (For reference, this benchmark included Meow, t1ha, Falk, xxHash, Metro, City, and Highway, since those were the "fastest" contenders that had public implementations available I could build).

        That is where data no longer fits in the L3 cache, so the task becomes memory limited.

        Any chance you have a comparative speed graph (bytes per sec?) rather than just the winner?

        Isn't 1024s for kibibytes/mebibytes, etc? Kilo/mega are 1000s (because they're si prefixes)

        Any chance Meow Hash could be used to implement a good fast PRNG (even though it's not designed for it)?

        A better idea is probably to just design a PRNG using the AES instructions in a similar fashion, I know that some people have already done so, I don't know if any of the results are good.
