I would have a look at perfmon, checking network and disk related counters, in order to locate the bottleneck. (assuming you are running windows!)

I'm doing a lot of moving large files among machines, and it takes quite a while. But, is the speed more determined by the target machine's hard drive? The network speed? Something else? Most of the machines in my domain have ordinary ATA/100 7200 RPM hard drives. It takes about 23 minutes to move a 4.3 GB file from my machine to another. I have one 16 port switch and four 4-8 port switches I'd have to replace, so before incurring that expense, I'd like to know if there'd be any real benefit to it. Thank you, Ray at home
