RE: Sluggish Performance

At quick first glance I think your issue is disk related.  The numbers
that you mentioned seem very high.  Definitely much higher than what we
experience.  Make sure you do some different time slots - 1 min, 2 min,
5 min.

You might want to also supply your dspsyssts information and qualify
what is sluggish?  Everything?  Interactive?  Batch?

Subject: Sluggish Performance

I've looked at the archives and tried some of the solutions there first
before posting.

 

We're experiencing very sluggish performance.  Our CPU utilization is
pretty low most of the time 20-30%.  WRKDSKSTS reveals our I/O running
40-60% Busy with gust to 80-100%.  Actual job through put is pretty
slow.

 

This has happened recently all at once.  We had added some new
subsystems and the sluggish performance started.  The slowdown caused us
to take them out.  We're still slow.  I don't know if the subsystems had
anything to do with the performance.

 

Any ideas or things to check would be greatly appreciated.
