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 ?
[I snipped out most of the CCs (again).]
I haven't been able to get a TCP connection to saturate a 1Gbps link
in both directions simultaneously. I *have* been able to fully saturate
2 pro/1000 NICs on the same machine using pktgen, so the NIC/driver can
support it if only TCP can run fast enough...
