In case anyone else is struggling with this problem I found that using the
latest beta mvel jar (beta 6) helps a lot. Performance and memory use
building and loading my large KnowledgeBase is much better- on my slower
machine I'm down to 20 minutes (from 60) of compile time. Not back to Drools
5.1 (10 minutes) speed. and I still have to give JBoss extra memory to
deploy my webapp, but still much better.
