It is not really easy to perform a comparison for different OS and different computers when using Photoshop, after having tried different solutions, I have been using a script provided by driverheaven.net.
This script carries out a test including 11 Photoshop functions on a 30MB RVB image file, I have tested this script on MacOSX with an iMac G5 1.9Ghz, PowerMac G5 2×2.5Ghz, MacBook Pro 2×2Ghz, and on WinXP Pro with MacBook Pro 2×2Ghz using Boot Camp and a Shuttle Pentium IV Hyperthreading 3Ghz.
Hereafter are the results in seconds to perform all functions/filers:
