"if" verses "elseif" - performance question

If those three checks are all mutually exclusive, I'd change the iRule so as few of checks are performed as possible. ie, if it's a request for / and you don't need to check for the IP addresses, either chain the checks in an if/elseif/elseif/else chain or use the return command to exit that iRule event in that iRule.

Chris' suggestions are also good points to consider.
