Another thing you could do is set the caching controllers and the caching tools to a different cluster. This should isolate the caching process from the regular pool of processes. I have seen this yield better performance isolating caching from regular arcgisserver functions. I typically call this new cluster caching. Then when you add new machines to your ...
