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. Anyone running this on a Quadra 840AV with the 68040? -- Yuki Watanabe "There are 14 nodes and only 10 countries. Count again."

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