I've got a Cisco FastHub 600 in our rack that connects to our support dept. We got 2 new Dell Dimension 2350's with Broadcom ethernet controllers. Long story short - Terrible network performace - Links that take 1.5 sec are now 25 sec. - Solution? We put a D-Link $49 special switch next to the new PC and bang back to high speed performace. The Broadcom card is 10/100 the switch is 10/100 the Cisco Hub is 100 only. I've tried going into the software (XP pro) and chaging the network card to 100 half and full instead of Auto but no success. Any ideas on why adding that switch in the middle would take care of this problem?
 
If it's a lot of traffic, then it would be slow. Remember that a 100Mb HUB has 100Mb shared between all of it's ports, and can only run in half duplex. A 100Mb switch has 100Mb per port and can run in either half or full duplex.

I wouldn't ever connect my servers to a HUB. If you must use hubs, stick them on the end-users. :)
 
Its actually very very little traffic on this particular network. We have celeron 800's that when plugged into the same network port as these new Dell's (2.3ghz) completely blow them away. Its a very odd situation. One of programs we use on a daily basis from the network has a login screen that is a 20k .exe file. On every computer but the 2 new Dell's it takes <2 sec to come up. On these new PC's it it closer to 20 sec. Everything locally on the new machines runs fine.
