MachineClaw- a couple / four guys did run times with bigger buckets, saw big improvements. I'd guess this is memory related, but if you have 1GB or more you should probably 2x or 4X your bucket size. The test is useful for seeing the difference, but only time the first run, the bigger buckets seem to take awhile to clear out the old render on the second or later try. The bigger buckets are invalid for comparing CPUs, of course, but useful for getting Poser 5 to run faster.
