You might also look at this simplified I::C hash. I'm sure it is slower than Perl's hashes, but it is also more compact if space is a problem.

And if bloom filters float your boat, then my 10x32-bit bit-tables from 1x 64-bit hash technique described in this thread might be of interest. You only need read my posts for code and roboticus' for the stats; the rest are noise.
