It is incredibly important to specify scopes. An example of it making more than a little difference: If you do an isDefined() on a variable, and its not scoped, and it doesn't exist, CF will methodically check through all the scopes looking for it. This includes the CGI scope. When it checks the CGI scope again, it will actually requery the Webserver for these values and fetch them again, just incase they've been modified. That will slow you down quite a bit and is something to avoid.
