Now, I assume that on Gigabit ethernet, I should be getting Line Rate,
which is around 220 MBps. Even the CPU is not getting max-ed out here
and I am at a loss to understand this behaviour.

Make sure you are running 64-bit 100+Mhz PCI, otherwise you will not
get line speed.  ethtool -d [device]
may get that info for you.

Thanks for that Ben. I now used a 64 bit,133 MHz PCI-X on both
machines and I got around  180 MBps, (86259.48 + 95164.90 ), which is
still a decent way away from Line speed. I think PCI is not a
bottleneck now, although I could be wrong. What could I be missing,
and has anybody seen line speed ( 220 MBps ) with e1000 ?
