Re: WRKSBMJOB, WRKUSRJOB slug-like

[eric.delong@xxxxxxxxxxxxxxxxx]

     Dan, do you have a large number of jobs hanging around with spool 
     files? If your job tables have been extended, you will see very 
     long waits indeed on the "job" commands.

Good grief!  WRKSBMJOB & WRKUSRJOB are absolutely slug-like on this V3R2 system.
 It can take up to 30 seconds to get a response, everything else (i.e., WRKSPLF,
WRKACTJOB) is at or near sub-second response.  This on a system where the CPU 
usage is 8.2% for a two minute interval (right now).  Is this a V3R2 issue?

I recall getting 2- or 3-second response with WRKSBMJOB even on some RISC boxes,
and had resorted to using WRKUSRJOB JOBTYPE(*BATCH) to get the subsecond 
response.  Either way, on this V3R2 box, it's a painful wait for someone who's 
used to getting it FAST.

Anything I can do to improve on this?  Cleanup of some sort?
