Well, what kind of hardware were you running?

How many disks? What kind of RAID controller? Which CPU Feature?

12 disks. I'm not sure of the RAID or CPU feature. But can those really be the bottleneck? It took 12 1/2 hours to transfer 12GB of data. Even a single disk can perform better than that. This system wasn't doing anything else all night.

Other issues could be a mismatched duplex setting - ensure that both
the switch and the ethernet line description are configured the same
(in most environments, *AUTO/*AUTO is the way to go).

I have *AUTO/*AUTO and it is currently at 100M and *FULL which matches the hardware capability.

if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
