Thanks  Justin and Miguel

Miguel for the client we are using those recommended settings, they have
been in place since we started backung up the clients. As for the TSM
server settings I don't believe they need to be adjusted as we have many
other clients that are running fine.

Thanks

           compression             yes

Server TSM

     - Set Ethernet speed and duplex settings (Don't rely on Auto Detect)
     - Specifies

           BufPoolSize       131072 (for server with 1 GB RAM)
           UseLargeBuffers   yes

           tcpbuffsize       32 (recommended)        2048 (max) in KB
------ Use up to 3/4 of real memory for a dedicated TSM server

(no other applications).
           tcpnodelay        yes


And  Use dedicated networks for backup (LAN or SAN).
