[rules-users] Hints for profiling pattern-matching

Folks, I am currently tuning a Drools application. We have made good progress with basic rule tuning (pattern reordering), however I am under the impression that there is still some inefficient matching going on. I am wondering whether there are hooks in Drools (or an approach) to get a handle on where "expensive " matching is performed. A regular profiler is not helpful, as I can't see the data (what is being matched). Any ideas? Cheers, Ingomar
