Thanks. It's working on my test VM after running a #depmod -a However,
after a reboot you have to do #depmod -a again. Then relogin your targets.
ext3 filesystem, noatime, read ahead set to 8K, Jumbo frames set to 9000.
It's a few MB slower with standard frames.
A quick 'dt' run with one GbE interface.
