The bottleneck of your application is to your database server. You just added a
hit to every persistant variable to your database. This makes your application
much slower than

You raise some good points. In your opinion if I'm not running in a clustered
environment, are session variables the way to go? Anyone else have thoughts?

I would venture to say that if you are or are not running in a
clustered environment, client variables are the wrong way to go.
As for changing your current aps, I'd say only do it if you begin to
see problems. When the load on your servers increase, make sure you're
monitoring general CPU usage

I think there are quite a few variables that need to be considered as others
have mentioned. I always use session scope on my internal work servers.
If on a shared server, one thing to keep in mind is that any other developer on
that box can see your session variables. Not good if dealing with
yes, but CFCs in the session scope can't be shared in a cluster.
Note, if you have a sticky session cluster setup, then this works fine, eh?
