I have RS/6000 SP2 wide nodes running AIX 4.3.3 and TSM 3.7.0. We do backup
Informix database level 0 twice a week and Level1 on remaining days using
TDP. My observation is TSM amounts for 15-20 % CPU power when backup is
going on.

In your case what is the application you are running ?

In AIX you can run vmstat command and observe last 4 columns. You should
atleast sample 10 readings to get the feeling. If performance Toolbox is
loaded , SVMON is the utility to get more detailed analysis of resource
utilisation.

You can also register yourself in AIX user group on
