Now here is the bench mark to time:
Filter >> Blur >> Radial Blur:
Amount = 100
Blur Method = Spin
Quality = Best
Click OK and time the process.
Notes:
(1) I found that adding the noise (or any other content) didn't significantly change the radial blur time. However, having the noise there does help for your to see that the filter actually worked when you stop your stop watch.
(2) I was surprised to find that going from sRGB 8bit to 32bit only increased my processing time by about 2x. I decided to make this benchmark pretty intense so that in the future few years when this poll is archived, we can still use this benchmark for comparison.
(3) The radial blur filter is a processor intensive filter. On CS4 it is well multithreaded (I'm not sure about other versions of photoshop) and can use all your cpu cores and virtural cores. I am not sure if CS4 utilizes help from graphics processor for this filter.
(4) The 8000x8000 32bit image will take at least 800mb of RAM so if you have less than 2 gigs of ram, this benchmark is probably not for you.
(5) I am very very interested in seeing how photoshop on MAC compares with PC with similar processors. Please list your computer hardware specifications if you know them. (e.g. PC - Core2 Quad Q6600 @ 2.67Ghz with 4 Gigs DDR800 Ram - Benchmark: 6:00 min)

Okay, I got another data point, but arrived at it a little differently.
My laptop with 2.5GB of Ram was unable to do the above benchmark because of insufficient Ram. Instead, I had to change 64-bit to 8-bit and that took 9:01 min. Assuming the same approximate 2x scaling in processing time to 64 bit, this would have taken 18 min to complete.
Mobile PC - Core2 T7200 @ 2.0 Ghz w/ 2.5GB Ram @ 667Mhz - Benchmark: >15min

Questions:
- Are you tracking which version is benchmarked?
- Is this filter multi-threaded or single-threaded? How does this change in different versions?
The largest difference in modern computers is increased number of cores - if the synthetic benchmark is single-threaded 3 years of computing progress will net almost no improvement.

My home-built C2d, overclocked from 2.4GHz to 3.6, and with only 2GB memory ran an extrapolated 3:45. I had to downsize to 5k x 5k, which ran in 115 seconds. Otherwise, I run out of memory.

I would expect a significant decrease in times with OSX 10.6 and whenever Adobe gets to CS5 which will be 64 bit for the Mac.
From what I have read, Snow Leopard looks to be quite a bit quicker. However I am unsure how much benefit we will see in CS4, will be interesting to see though.
