Egg on my face -- disk speed

The numbers for the test in case are currently about 34% cpu for the
disk to /dev/null and about 64% for disk to disk.

I can't remeasure the tcp numbers I don't have the hardware anymore.

The same test on a rather busy freebsd machine yields 2.6% cpu for the
disk to disk case.

In both cases the second disk was a file system on another drive.
On the same controller.

For tcp, with my k6-200's I never got much about 8megbytes per second, but
could do the same with P120's running freebsd.

Since I can't currently do the tests, I will have to retract my
numbers in the face of people who have current test results that show
different numbers.
