The hash is not the only part to consider for performance.  The rest of the
code is important as well.  The code I pointed you to has been really carefully
tuned for performance.  And it can be made to be MP safe, SGI did that and
managed to get 455,000 random fetches/second on an 8 way R4400 (each of
these is about the same as the original Pentium at 150Mhz).
