system faulting after memory increase

[Sanjivji AT Gmail <sanjivji@xxxxxxxxx>]

Have a 570 system where memory was increased from 8Gb to 12 Gb
The faultings have increased
Here is a snapshot for Sharepool / WRKSYSSTS/ Subsystem description
The qpfradj is set to 3
Most of the pools have Min/ max defined ?
Will having  Subsystems defn set for   Base as Pool 1 help as all the work
through Task Dispatcher goes via Base only ?
The Routing entries for all subsystems point to pool1

Is there anything that can be done to lower faulting rate
