Has anyone had experience with TSM backups to a TSM server on Z/OS. 
During the backup window the user online access is significantly slower.
Also the TSM address space takes a large percentage of the cpu.

Would a dedicated TCP/IP address stack for TSM help
WLM tuning, not an expert, the dispatching priority of TSM is lower then the 
online and database address spaces

Suggestions !!

I am looking to migrate TSM server off of the mainframe but that wont be for 
awhile.
