What is your hard disk performance like? I think you can figure that out 
by running hdparm; such as:

"hdparm -t /dev/sda"

and you will get:

/dev/sda:
 Timing buffered disk reads:  64 MB in  2.45 seconds = 26.12 MB/sec

My guess is that if your CPU util is low, your hardisk might be the 
bottleneck. What is that number and if it is low it could be due to DMA 
not enabled on your harddisk or poor hard disk performance.
