Dave, Another possibility:
Perhaps all of the instances of the persisted CFC merely carry a name/pointer pair which points to a singe stale copy of the method and hence Sean's statement still holds partially true regarding not taking up a "great deal of space". However, I'm merely making a similar conjecture.

Thanks very > much! While that may be what you wanted to hear, I have my doubts about it. When you create an instance from a CFC and put it in a persistent scope, then change one of the methods within the CFC code, the instance doesn't use the new code, but rather the original code that was there when it was instantiated. This leads me to believe that it carries its own copy of the method code with it.
