the first message was a follow up to other messages as a real
world application performance issue. As I stated
earlier, I did not focus on bringing this application to the max
on every system, but to use an existing system and see how it goes.
I know this general process of 'yes this is the current status but
we have a bunch of fixes which will help you' very well.
I also can read between the lines of some postings, too.
