Ok. Personally, I don't think this is a huge gain, but I guess it is indeed pointless to argue about that one.But how will you find it there? If you are going to have 740K blocks (i.e. - 740,000 strong hashes) in a 16bit hash table, you are going to have lots of collisions there (190 per bucket, on average), and you gained nothing.
You'll note that a no-match bitmap has no effect on the normal hash table lookups, so you're railing against something that is not even discussed in my email.
What about my proposal, though? Should I send in a patch so it can be evaluated (hoping I'll manage to find my way around, that is).
