Compiling stardust.c with Think C 6.0 vs MPW C with direct 68882 inlining.

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.

My 14.4k connection dropped twice trying to fetch this thread. Keep articles concise!
