Another consideration is the amount of data you're passing around. Since a
registered variable will only be processed locally, and not transmitted over the
internet, registering variables will cause your pages to be smaller, thereby
transmitting and loading faster. 

The speed up is of course marginal in most cases, but I recently had to pass ~8K
of data around, and registering that data sure made a difference :-)

Hope this helps
