:Can I ask why is there a huge difference in the number of io (251k vs 4k)?
:What is so different between 4.0 and 5.0 that causes this?

Ha! I found it. Kirk gets the credit --- softupdates was turned on
in one of the machine's /usr/obj's and off on the other machine's.
So softupdates improves buildworld times by a significant margin. I've
turned softupdates on on both machines and am rerunning the test. I
expect I will see an improvement closer to what Bob Bishop saw when
he ran the test (7% or so) rather then 20+%.
