Here is what I got by running Bonnie with no args supplied to it:

              -------Sequential Output-------- ---Sequential Input-- 
--Random--
              -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- 
--Seeks---
Machine    MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU  /sec 
%CPU
          100 26708 98.1 388265 100.1 359183 99.3 25465 99.9 577477 99.3 
32604.4         97.0

I ran the above on /dev/hda2 (about 7-8 gigs into the disk), and by using -d 
and using a directory on the last 15gigs of the disk, I got about a 6 meg/s 
reduction on the per char sequential output, and about a 20 meg/s less for 
the block sequential output.  I, too, have astronomical CPU usage.
