Our Netbackup infrastructure is based around an E450 with gigabit
connectivity.

For some reason, it is impossible for us to get a throughput on the (ge)
Gigabit card of greater than 10Mb/sec. We have tried a direct connection
between the server and an E220R with a ce gigaswift card, with exactly the
same results (therefore ruling out the switch).

We have tried using Netbackup, ftp, dd (with remote shell), but all showed a
similar throughput.

The autonegotiation on the device has been set both on and off, with no
change, the messages file indicates that the link is up at 1000Mbs full
duplex and I am totally out of ideas.

Can anyone suggest what else we can try.

Thanks in advance for any replies.
