These numbers look promising, but maybe some more regid experiments are 
needed to quantify the benefit of page loaning in NFSd.

Here is what I suggest :), I am a lazy bum..

First make sure the big file is in memory. Second, what is the CPU usage 
w/o the NFS experiments? Third, if possible, try Gigabit ethernet...

All mumbo-jumbo, you can just siliently ignore it.
