Well you do not mention if you've diabled WITNESS and INVARIANT stuff.
'cause if you want to benchmark, that is what makes a big difference.

Look at the graphs I made for some simple NFS benchmarking at:

where especially the reading blocks makes a big difference.
Even more so, when the data is still in memory.
