This is probably a strange question, but is there a way to reduce WLM cpu 
usage?   Here's the situation: 

- The system is a lightly used development system.  Unless something is in a 
loop (very rare), CPU % probably is usually less than 10%.  And except for 
system regions & CICS, it's rare to have multiple jobs running concurrently. 
- Only one processor defined to the VM. No ZIIP either.  
- We are charged for CPU cycles.
- WLM is the highest consumer of CPU.  JES2, TCPIP, ZFS and SDSFAUX round out 
the top 5 consumers. 

There is a lot of information about WLM tuning, but as best I can tell almost 
none of it relates to reducing WLM usage.

From reading the Init & Tuning manual, I'm trying these settings: 
AIMANAGEMENT=NO  
HIPERDISPATCH=NO 
CCCAWMT=450000   
RMPTTOM=15000    

I was thinking that perhaps reducing whatever processing intervals I could 
might help.  But I can't tell these changes made a difference.  (I don't have a 
tool to measure WLM usage.)

Any suggestions would be appreciated.

TIA,

Wendell
