Re: System slow

Well hopefully you have collection services running (as part of PM iSeries)
if nothing else...

If you have the performance tools licpgm, you may be able to see something
via the iNav plug-in.

Assuming you have IBM support, you may want to just open a PMR and let them
dig into it.

Or perhaps you have MPG's tools...

And if not, consider downloading a trial copy.  You get full features for
30(?) days, which may be enough to dig into your issue (again assuming you
had collection services already running).  IIRC correct the tooling is
pretty reasonably priced.  After that, you get a free basic subset of
functionality that's kind of useful.  More useful is the automated
consolidation of collected data.

As a last resort, you can query the collection service data tables directly
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/rzahx/rzahxperfdatafiles1.htm

Google for example queries...but be warned it's not for the novice. :)
