I don't know. I do know that I've been able to speed up some of the other
algorithms by as much as 3 to 4 times; Others do not lend themselves to much
improvement. I haven't seen the C implementation, so I don't know how they
do it in C, maybe I could get a hint to make it work faster in FPC.

I think that this one should be answered by the compiler boys, as I'm not
very familiar with the way the code is generated.
