I am currently writing a paper on exactly this topic. It should be
up on my web site by the end of the week:

I have benchmarked this and achieved speed improvements on Pentium II, P III
and AMD Athlon processors of 6-10 times.
The benchmarking code will be made available for independant verification. Also
included is a cross platform header file so that similar speed improvements can
be achieved on Win32. If I had access to a Mac system I would like to add
support for that as well.
