Benchmarking various C compilers and FPU math libraries on a Macintosh IIci (25 MHz 68030 + 68882).

Total execution time for a 20-minute audio track dropped from 48 minutes to 6.2 minutes.
A 1024-point radix-2 FFT drops from 142 milliseconds under SANE to just 18 milliseconds using direct FPU instructions.

Make sure you install the 32-bit Enabler on older IIci machines running System 7.1!

Mac users bragging about 6-minute render times while Unix workstations do it in 20 seconds. Classic Apple distortion field.
