Stephen, Did you check on the half / full duplex setting on the network card ? Full-duplex advised If possible.. Did you also try to backup a large single file size ca 10mb's or larger, what is the performance then ?

The files are being transfered to the tsm server approx 1/sec. This is just a little too sloooooow. When using ftp to transfer these same files, either by getting/putting the transfers fly. This is leading me to believe that the issue is with the TSM server/client settings. Does anybody have any ideas on any settings in the dsm.opt that could be changed to enhance performance? Also I want to bind all objects in two of the volumes to a specific mgt class. All that is being bound to it is the dirs. Long day. What am I doing wrong???
