Use attribute-to-script connections judiciously. Using attribute-to-script connections frequently may cause your application to run slower because of unnecessary connections. Although there is no hard-and-fast rule to follow, perhaps a general example will help you.

Let's say that you want to change the value of several text-entry fields each time some event occurs. You could create an attribute-to-script connection for each field. Each of these connections would run separately, which might take considerable time.

On the other hand, you could create a single event-to-script connection that updates all of the fields from one script. Since there is only one connection and one script, this approach will probably yield better performance.
