Mine does it in 8 seconds... tried it a couple different ways with no difference.
I'm wondering what system you have.
I just finished building my new system and got 11 seconds with the radial blur and 16 seconds on the Retouch Pro test. I did have things running in teh background though, like Anti-virus, etc., but that should not affect performance.
CPU: Core i7 920 @ 2.7Ghz (no overclocking, but that is coming
MB: Gigabyte x58 UDF5
RAM: OCZ Triple Channel Performance Series Matched Set @ 12GB
PSU: 1000wt Kingwin Mach 1 Moduler
Disks: (2) 640GB Western Digital Caviar Blacks in RAID 0
Test: Radial Blur 11 sec
Test: Retouch Pro Eagle: 16 sec
From my old system listed above, I tripled my performance in the radial blur and quadrupled it in the Eagle test.
