Last night I found out that we restored about 850MB to a disk that was
replaced. Of course it came straight from tape so the speed would be slower.
They told me they were getting about 300k per second transfer rate. I'm
wondering if this is normal rate of transfer given the following:

Client is running SUN OS with only a 10mb ethernet card connected through a
100mb switch.

This is a backup of data before the disk replacement:

This is from the log on the restore:

It looks to me that the transfer rate is close to being the same in both
directions so I'd guess the problem lies with the network card that the
client has in it. Since it can't be configured to 100/Full it's going to be
much slower. The question is if the switch is set to the same rate the card
is 10mb is this backup and restore normal or slow?

Any info is greatly appreciated.
