Thanks for spending time on this. I would like to understand what "really bad" and "fails most of the tests" means.
For the record, the commit: https://github.com/rurban/smhasher/commit/10f56385f3e9abb018...
The main point of this hash, in this context, is to do streaming hash and find \n at in one loop. The intention is to reduce data loads _mm_loadu_si128 (I already have user data in xmm0, so why not do some aesni already?). Because it's streaming I can't for example derive the initial seed based on the chunk length, since it's unknown at the time of calling hash. See:
https://github.com/cloudflare/cloudflare-blog/blob/master/20...
I don't need full aes hash, but maybe that could be an option as well.
In other words, in my case I don't care just about hash() speed. I care about memchr() + hash() speed. I would like to understand/measure the hash quality itself. Maybe adding another aesenc round would be sufficient to fix it.
