It has always been my opinion that the CPU Utilisation and Page Swaps rules are highly variable, and therefore do not often represent the real load of a server. CPU Utilisation can often be too erratic to provide consistent load balancing. Now days you have the CPU Optimisation feature, or a 3rd Party management app controlling this. Once you’ve base-lined your systems, then a custom evaluator with the Server User Load and Memory Usage rule is about the best to receive a consistent balance across all servers.
