I'm still mainly in the dark. It appears that your main problem is that
the optimisation job has slowed down to a crawl on the update-2 cluster.
But then you start talking about a linked server. I can't see how the
optimisation job can be affected by the presense of a linked server.
Are these servers all part of the same application and are hosting
similar databases? Or are they completely different from each other?
