How we sped up random forest processing, lots of common performance patterns

In the previous article we outlined our problem, the major constraints we must adhere to and wrote a straightforward implementation of a random forest evaluator. We proved the correctness of the implementation and then we set up a naive benchmark to test how much time it was going to take to run 5,000 samples through 1,000 trees, each of a maximum depth of 5 decision nodes. This currently runs in about 320 ms and we need it to run in about 25 ms.
