I prefer using QPFRADJ. But, remembering from the debate, I think if your
load changes drastically then it takes QPFRADJ awhile to catch up. I think
someone said that it will only adjust a certain amount within a certain
time period to not swing too far one way or the other.

I was curious about the Performance Survey last week. I got the impression
that the majority favored manual tuning of the system vs. automatic
performance adjustment via QPFRADJ. Personally, I have been a fan of
QPFRADJ ever since it began using less than 1% of the CPU.
1.) What can I do to manually tune the system, that QPFRADJ cannot do
automagically?
2.) Why would I want to spend time manually tuning the system when I can
set up the basics and let QPFRADJ take care of the day to day(or hour to
hour) fluctuations?
Or does the majority favor setting QPFRADJ to 2 or 3?
