John,

Ooooh.  You did a pretty much equivalent swap on boxes.  Most CISC-RISC that
I've heard of upgraded the target box significantly over its CISC equivalent.
 We went from a 320 with two processors to a 530 with four (and nearly twice
the DASD) with no performance degradation.  RISC runs batch jobs faster, and
interactive jobs slower.

Yeah right!  SSA, who won't "certify" BPCS for RISC or security level 40, is
going to "fix" your performance problem.  Is this the SAME SSA that replaced
CHAIN statements with SQL single record FETCH statements to "improve
performance in the UNIX environment, no effect plus or minus on the AS/400"?

You didn't mention your release level, but I would suspect SSA has something
to do with your performance problem.  Per earlier posts on MIDRANGE-L from
others, I'd also check the value of the QDYNPTYSLT (sp?) variable on the RISC
box.  The latter changes a job's priority at the system level based upon the
processor's perceived need, and DOES NOT show up in the job's viewable
priority.  I assume that you are NOT running factory presets for memory pool
allocation and subsystem pool assignments.  If you're running a query tool
and/or one of the SQL-intensive BPCS releases (5 or 6), you might also want
to check into activating SMP.

That's all I can offer on the information given.  Feel free to write directly
if you have more specific questions...
