Client Access and a slow system

We are currently running V3R2M1 of client access using NS/Router and it
appears that client access has a lot of overhead.  There are over 60 jobs
under QCMN.  (Below is a sample.)  Is there a better way?  Can we have just
one or two sessions under QCMN to save overhead?  What is QZSCSRVR?  Etc.

Any help will be appreciated.  Thanks.
