I was expecting some ridiculous time, wouldn’t have been surprised if it took longer than the install (I won’t name the MS apps that have). But still it did take quite a while on my 2.4GHz P4m with 512MB of RAM and the 5400RPM laptop HDD. Another note is that the 1.8GHz P4 MCE with 256MB of RAM finished the batch process in Photoshop of auto touching up 4360 photos and resizing them in just a little less time.
