About 3-4 months ago, there was a thread where people posted their times for doing some manipulations in PS on varying platforms. I have tried in vain to search for this thread, but I keep coming up empty. By chance, do any of you have this thread bookmarked, and if so, could you please paste the URL? I wanna see how my G5 is stacking up. thank you.

EDIT:
Ok, since CS2 is out, I want to see if numbers are different. I hope isyukri doesn't mind me resurrecting his thread (please let me know if you do), but here goes. Please paste your results from CS2 (since CS1 was covered quite well in the first post linked by Olnibrcn).
1. Left click on the image and save it on your desktop, it is 87.6KB size.
2. Open image in Photoshop and resize "Width" to 2000px, the "Height" will change automatically, then click "OK".
3. Click "Filter - Blur - Radial Blur".
4. Set "Amount" to 100. Then select "Spin" and "Best".
5. Do not forget again to select "Best", if you choose lower, the processing time will be shorter and you will not believe speedness of your system ).
6. Be ready with the stopwatch. Click "OK" along with start button of your stopwatch.
7. Record the time needed until the progress bar in the lower window of Photoshop disappear.
8. Report the time in seconds along with a bit information of your system.
Tips:
Closing another programs and let Photoshop the only program running will speed-up processing time considerably. ...Show more →

You're welcome,
I was looking for info on scratch disks. Ran across your question, the next post I looked at was the thread you were looking for... it was eerie. I ran the test and that was depressing. My three-year-old Pentium 1.4mhz, 640meg ram, ran Best mode in 3 min. 17 sec., Good took 19 sec., and Draft was 7 sec. The times in the original post were less than half of my computer times. I think I only beat out the laptop speeds. How did your G5 do?
I'm pretty ignorant about how PS uses memory and scratch, but the efficiency in PS never dropped below 100% in my test and I "think" that means that the whole operation took place in ram. The scratch disk did not come in to play. I do see the efficiency drop as low as 60% on my system when running other operations which evidently indicates that PS is writing to scratch.
Am I correct on that? And if so, do any of you hardware geeks know of a good way to quantify scratch disk performance? I've timed various operations that seem to indicate scratch use and the results are inconclusive.
I've seen numerous reports of people claiming that they have increased speed by setting PS scratch to fast external firewire 800 drives, but in my experience this provides little or no benefit and in some cases actually slows things down. Especially if the externals automatically "spin down" due to inactivity.
