First the obvious things:
What' the performance like when you try to ftp a file to the TSM server? If
the ftp is also "slow", then the problem is not with the TSM client.
Some tuning considerations for the TSM client:
txnbytelimit (in the client dsm.sys file) should be 25600
txngroupmax (in the server dsmserv.opt file) should be 256
also for the following:
TCPWINDOWSIZE
Specifies TCP sliding window size and allows multiple frames to be sent
before an acknowledgement is obtained from the receiver
Requires increased memory on the client
Recommendations:
Minumum of 32
Increase this size accordingly - start at about 2048 and work upwards
Experimentation required
TCPBUFFSIZE
Specifies size of client s internal memory buffer used to send to the
communications layer
Used by client only during backup; used by server only during restore
Requires increased memory on the client
Recommendations:
Minimum of 32
Increase this size accordingly - start at about 2048 and work upwards
Experimentation required
