performance issue

We have a AIX v5.3 on a p5 system with a poor performing Ingres database.

We added one CPU to the system to see if this would help. Now there are two CPU's.

with sar and topas -P I see good results: CPU usage around 30%

with topas I only see good results in the process output screen, the user still consumes >90%

with: sar -u -P 0,1 both CPU's report around 80-90%

with lparstat I see 51%

with lparstat 1 5 I see >90%

What is the actual performance of the system?
