It's true that OA09229 will fix the lion's share of the additional overhead caused by sending messages around the sysplex (it eliminates the automatic multicast of all messages), but if you do use the ability to route messages around the sysplex, OA08482+.FORNSSI *NONE will reduce CPU in the CONSOLE address space by preventing these messages from going to subsystems that will not have any interest in processing them. I hesitate to make this a 'best practice' since I am not aware of any study to determine if it always safe to turn this switch on. I'm sure there are subsystems that want to see foreign messages (i.e. focal point automation).
