[rules-users] Perfromance issues and memory leaks in Drools

Hi,

                I have written 2 different Drools programs. One is with Using rule Base of Drools 4.0 and other is using Knowledge Base of Drools 5.0.
I was trying to check that is there any improvement in Drools 5.0. But I haven't got any performance improvement in Drools 5.0 code compared to Drools 4.0.

                One more important thing is I am calling this drools code from  My application which itself is heavy application, when I am doing Performance tuning
I got one point i.e. session.execute() method is taking around 6-7 seconds to initialize rules and even the memory utilized by Rules is huge.

So is there any way that we can reduce the Memory leakage and improve performance.

Waiting for Reply.

Thanks & Regards,
