Mark, That's an excellent suggestion, inasmuch as we have a couple dozen of these servers running and, if nothing else, sharing code could reduce overall demand for memory. Obviously, the bigger win would be if this is the code that is actually being paged in and causing the delays, since by sharing it would be more likely to be in storage already. The larger problem is going to be getting buy-in from the app owner to implement such a thing. Best regards, Mark
