I also believe the actual proxy CFC code should only be generated once. However, since I haven't used AOP with a non-Singleton ColdSpring-managed object, I am not 100% sure. Are you sure what you want to do can't be handled with a Singleton using AOP (that internally may interact with a per-request CFC), rather than a per-request CFC for everything?
The only "performance issue" with using ColdSpring for per-request CFCs is the overhead that ColdSpring goes through checking for any dependencies that need to be wired up. ColdSpring internally caches all of the bean definitions and their dependencies internally, so the overhead is fairly minimal. However, if performance is an issue and you are trying to generate large numbers of per-request CFCs, you're probably better off writing your own factory to create them (and have ColdSpring inject the factory into the service objects that need to use it).
