Have a customer who has some Kingston KNE100TX (i.e. 10/100 auto on UTP) cards in some Umax (Mac clone) machines all 604e 180/200MHz CPU's.Running the latest version of the NIC driver and on OS8.0. He seems to be getting very poor performance even though it seems to be negotiating at fast ethernet speed. The LED on each NIC confirm 100MBps. He has these machines connected via a switching hub. It also freezes 1 or 2 or 3 machines during a long transfer.
Behind the switch is a larger network of MACs (and PC's) as well as a Win NT 4 server and Netware 4.11 server.
Well, an interesting experiment was conducted. We removed both Apple talk and TCP/IP from the Control Panels folder. Well, the machine was still able to log on to a variety of other machines as well as the Internet. (without TCP/IP !!). Could one or both of the servers be routing the information through? And therefore, with those Control Panels enabled could we be having protocol conflicts?
Further, it only seems to be afflicting the higher end machines (604e processors, 180/200MHz). The 200MHz 603e UMAX's seem to be immune.
Also, what are some reasonable transfer rates for both 10 and 100 mb/sec.
