Not to argue with your experiences, but my Advanced Floating Point Unit
has always performed dramatically better then the on-CPU card 68881.
Of course, I'm running AIX, have the fpu enabled in my kernel, and use
the floating point libraries for the system compiler if I want to bench
floating point. GCC produces crap for floating point on the RT.
