10/100 hubs. This is a small client, with limited hardware budget. So, it's a pair of 8-port 10/100 hubs, connected. > >I want to suspect hardware, but flood pings from a linux box put on the > >network never report dropped packets. > > > Then go back to hardware.

Good point. Wish I'd thought of that. I've found a new caveat, however. One of the machines in the office is absolutely unaffected by the problem. It opens extremely large files very quickly. I find that one user has been reporting the problem for several weeks, and now three more users have begun experiencing it in the past week. I cannot find any differences between the fast machine and the "slow" machines--except the fast machine has slightly older hardware than the slow machines. All are running Windows 2000 SP4. And, when I connected from my linux laptop using smbclient, transfers are instantaneous (or close enough) I'm beginning to suspect this is a client issue. The problem, however, remains, and the client would be happiest if I could make things fast again. > SMB is pretty chatty as far as protocols go. Yes, it is, but I did some big scp transfers, and would have expected to see at least SOME TCP retransmits if it's a hardware issue. Also, SMTP, POP3, and IMAP are very, very fast on the network--no delays whatsoever, while SMB traffic is not. I'd like to believe that a hardware problem would affect all protocols equally--but I'm not so sure about that supposition. The hubs were hot to the touch, I wonder if they're starting to fail. One of them is circa-1997--I know that's when I got the exact same piece of hardware as a promo from 3COM (an officeconnect hub).
