The IF rule evaluates each condition in sequence. The more conditions you have, the longer it takes. It is better to only use the IF rule during testing and implementation and replace it with a custom rule in production.
Turn off debug-related option by setting the Debug_if option to No in the If_Rule control group.
For more information about the IF rule, see the Rules Reference and Setting the Scope of Variables on page 40.
