[rules-users] fact problem

Hi, When i am taking a precompiled class in my rule engine is able to process any no of objects in very quick session. but when i am taking the facttype(class created from drl) inspite of precompiled class then it is taking much time as no of objects increased in the memory i have 6 rules in my drl 1- in case of factType it is taking 1 sec for each 50 when 30000 objects in memory(increases as no of objects increased in memory ) 2- but in case of precompiled class it is taking 1 sec for each 1000 .without much effect of the no of objects (i have taken 1024mb heap size) I am not able to find the cause of this problem . Please inform if you have any idea about this. Regards Saurabh
