"Thus, for code that is executed frequently, if not continuously, performance improves over time as more of the remapped code is resident in the cache. The thought of code that runs faster the more it is executed may seem counter-intuitive, but most IT professionals would have to admit that the thought is captivating."
You mean it's using the same idea as Java's HotSpot, except it's not using such a flexible intermediate language and the code has been optimised for a different architecture which will be difficult to undo. Don't get me wrong, it's brilliant for applications which have already started development but if you want it to be portable, use Java from the start. If your worried about Java's (alleged) performance issues then you will have the same if not worries problems with this method.
The thing which grates is that the HotSpot type technology is describe as if it's something really that new and special when it's not.
