Performance and iAsp

Few months ago we added 10 spinning disks in our IBM 5030E. The main
purpose is to provide a separate disk pool for large, rarely used libraries
and a staging area for creating SAVF's for nightly saves.
Of course we made a new pool on the SAN and we decided to use iAsp instead
of a normal Asp only because iAsp cannot spill into system Asp.
The majority of basic users don't see the new iASP because they don't need
it, on the contrary all the higher profiles use the iASP (via
INLASPGRP). For these profiles the problem I noticed is that all functions
that somehow use tables (or Sql functions) in QSYS2 have become slower.
Checking how they are executed it is quite clear that both the programs and
tables used are from the iASP rather than the system ASP.

So my questions are:
- If instead of using an iASP I had used a normal ASP would the problem
still occur?
- Could transforming the iASP into a normal ASP extend the problem to all
other users of the system?

The operating system is version 7.5 with recent ptfs.
