In application.cfc onRequestStart, I've seen the targetPage as
/flashservices/gateway.

How do I utilize that to make the call use an instantiated object to speed up
access? Currently the only way I know is to allow the service cfc to be called
(instantiated) with each call, and within it to call a scope resident cfc. I'm
hoping there is a way to use the application.cfc to skip the instantiation of
the service cfc for each call.

Obviously if there is a way I'd need to retain any passed in parameters. Thx
for any help.

Remoting calls - like web service calls - always create a new instance
of the CFC.
Are you really seeing a performance improvement by having your service
CFC delegate to a shared scope instance?
I ask because I ran a number of performance tests against my IRCbot
(an event gateway CFC - which is also created on every request). I
found no noticeable performance improvement from keeping a single
instance of the CFC in application scope and delegating from a simple
event gateway CFC to that shared instance, compared to just letting
ColdFusion create the CFC on each request.
You may be spinning cycles trying to optimize something that doesn't
actually need optimizing...
It's also worth noting that CF8 has *dramatically* speeded up CFC
creation anyway.

Thx, that is good to know. Your right, I had just presumed that an already
instantiated object would be faster. At the moment I have a service cfc that
include's the appropriate method on call, so not every method gets
instantiated. I'd assumed I would need to recreate this so that each method
would be a cfc on its own, and would get instantiated into a struct array of
objects the first time it is called and then recalled each time after as
needed. I guess I don't have to do that.
