Paging rates.

[msmith6@xxxxxxxxxxxx]

  I have an 810 with 12 GB and two LPARs.  The primary LAPR contains 
most of the resources, .85 CPU and and about 9.5 GB of storage.  
Everything seems to running fairly well.  I was reading through a 
Redpaper call iSeries Performance Management Tools earlier today.  As 
I was skimming the WRKSYSSTS page when I spotted a formula for 
a 'Rough Guide' to paging rates.  They said 100*(CPU Util./100)* 
Number of processors in the partition should be about the paging rate 
for all pools. I'm not sure why they would have just said CPU 
Util*Processor percent in Partition. Is this accurate?

That would make a CPU at 80% CPU util and .85 *only* have a rate of 68 
pages.  I remember, 'back in the days', there used to be a Work 
Management Guide that went through all this in addition to size your 
pools.  I haven't seen any of this documented in a while.

Any input would be appreciated.
