Yes, done.

I had saved the test results from the last set of tests and added the 
new results.

There is both a speed improvement and regression in reading depending 
on the test size.  I repeated the 2G and 3G test twice and there was 
very little change between tests, but it doesnt seem to make sense 
why 4G would be faster than 2G.  Also, this test if you recall, used 
to lock up the box with preemption in the kernel.  The version in 
HEAD, with the above patch works just fine in RELENG_6 using these 
simple tests and does not lockup.
