To be fair to OP, does anything about your current paradigm even allow you to evaluate his claims? Is your code even in a form that you can for example remove polymorphism and use simple arrays of data you want to work over? You can of course only optimize what you are looking to optimize. I am not surprised (honestly) that some engineers do not realize they are in fact primed for the kind of things they will find based on what they are looking by the mere choice of where they want to look.
