Re: [rules-users] GC Overhead Limit Exceeded and 1B JoinLeftNode Objects

Although I did see a drop in initial memory usage, things went south again as the run continued past the 2-4 hour mark. I have poured over my source several times and am starting to loose faith that Drools can provide anything other than a single threaded rules engine. Although the engine itself is fast, it seems it cannot scale from a memory perspective. I understand I am not providing much detail or a use case, but perhaps there are some official best practices documented somewhere on how to scale Drools? I cannot get valuable heap dumps because the heaps are enormous. I have continuously been told that Drools doesn't perform by colleagues and was hoping they were wrong. Any pointers or help is greatly appreciated.
