Total execution time for a 20-minute audio track dropped from 48 minutes to 6.2 minutes. Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow.

Mac users bragging about 6-minute render times while Unix workstations do it in 20 seconds. Classic Apple distortion field. -- Matthias Duarte US Robotics Courier V.34 @ 14,400 bps "Hold for relay."
