tsm overall performance is quite the order of network speed
i've been given the following data (to be verified)
1,4 GB/hour on a 10 Mb/sec net
14 on a 100
140 on a 1 Gb

some clues :
check your network (by doing remote file copy or ftp transfer)
check your clients backup logs : they will tell you how fast data has
been transfered on the network 
check your achitecture (disk pool, disk perf, tape pool, tape perf,
migration conditions...)
what about the server own backups ? fast or not ? (no external network here)
