I was doing some profiling on our application and a huge amount of time is being spent in the initialization of FMParser which is creating an exception called LookaheadSuccess. The way the exception is initialized many times, it will always fill in the stacktrace which is a very expensive operation and could be made much faster using a static variable. This has the potential to give KRAD a noticeable performance gain.
