We have a 2950T switch connected to 3550 12T switch.On the 2950T switch the 100BT ports are used for uplinks from other switches catalyst 2924xl. PC's on the switch FTP to server on the 3550. For a get they have speeds of 5000-6000 bytes per seconds but a put has speeds of 600Kbytes per seconds or less. There do not appears to any errors but there are deffered packets on the ports used as an uplink.
I also connected a PC to the 2950T switch and FTP's to a server on the same switch. A get was 10 times slower than a put (287.62Kbytes/sec. to 2936.69Kbytes/sec.). I moved the server to another 2950T connected in the same way and got the same results. I moved the server to the 3550 and the speed improved ( 3751.11Kbytes/sec.get to put 3102.20Kbytes/sec).
Are there performance problems with the 2950T's used in this way ?

yes i do have same problem. in my case i'm having a novel server connected to Cisco 2924. and clients are connected to 2924s or 2950s. all the 2924s and 2950s are connected to 4006. Now the problem is that user connected to 2950 does not able to log in to novel server, immediately. They do get log in after some time. In 2924 there is no such problem.
the delay in 2950 is 1000 usec, while that in 2924 is 100 usec. Has it got anything to do with it?
I have found a resolved caveat for my problem. This causes slow forwarding so could cause your problem but it says ftp. Up and try it
THe problem is resolved in 12.1(13)EA1b
When full-duplex mode is manually configured on a switch interface and on the interface of the link partner, the number of deferred frames in the show controllers ethernet-controller privileged EXEC command output no longer increments, and the switch interface now forwards packets. If you test connectivity to remote hosts by using the ping privileged EXEC command, ICMP packets no longer time out. If the switch forwards FTP traffic, the throughput rate is no longer low.
