Just a note for anyone interested, I originally took the Windows DLL 3.3.5
and benchmarked a particular query.  Takes 2.4 seconds on a reasonable
dataset.

Took the src, compiled up in VS.NET 2003, with lots of speed optimisations,
Pentium 4 and above, SSE on etc.

Same query takes 1.6 seconds, so if speed is your prime concern and you know
the target machine architecture, you can get some good perf increases by
compiling up the src rather than taking the binary as is.  And the binary
file is actually slightly smaller than the unoptimised DLL taken from the
site.
