I had similar problems and found out that TSM Server's NIC was configured as half-duplex. Interesting is that I wasn't having visible performance problems with unix/windows clients backups, but for Netware (high volume of data) the performance was terrible. Changing net card to full-duplex made a great difference and now Netware backup is very fast.
