I read a paper by Rick Strahl that says (as I understand it) that every time MTS receives a message, it instantiates the application object to deal with it, then releases the object again immediately. Given the many seconds that it takes VFP to instantiate some of my forms, this sounds horrible to me.

MTS packages have a setting on them to determine how long they remain in memory after execution is complete. Any subsequent requests for service from a front end will use the version in memory, not launch a new instance. The default for this setting is 3 minutes, but I have packages set for as high as 15 minutes.
It is not hard to tell when an instance is being created, and when one already exists. But, there is still only a half second or so delay.
