For myself, not to the 570. I was speaking in general about many model
upgrades/swaps and OS upgrade at same time. In some of those conversions
we did notice performance problems until some configuration issues were
resolved (for a variety of reasons, most have been listed by myself & others
as possibilities). In your previous postings
you have mentioned the configuration and tuning has been tweaked by those
working the problem.
What is it that leads you and others to believe this is a model 570 issue?
