Detecting application behavior dynamically is non-trivial. Commonly it is performed by instrumenting the binary, which _degrades_ the performance of the binary. The act of observation destroys the behavior to be observed, so to speak. This is why 3D marks vantage explicitly prohibits "Use of empirical data of application for optimization". _After_ you get the behavior of application, optimization is a lot easier.
