[rules-users] Scaling Drools based application

We have an requirement to scale the implemented Drools Rule Engine to all states in United States. With respect to the current implementation we have around 50 decision tables which when packaged creates a 200 MB pkg file and another pkg around 150 MB. The request which the drools engine consumes is a 150 KB xml file which is marshalled and processed. We have a JBoss server configured with 4 GB of memory (heap size + permGen) and works well with processing 5 concurrent request. Any request beyond 5 leads to OutOfMemoryException Now we have to scale this application to process request from 45 states, so there will be state specific pkg files (350 MB of pkg file). Each pkg is different for each state. With all this, do we need to increase the memory as no of states * 4 GB. Is this assumption correct? Is there a better architecture to handle scaling of drools application. Any memory/performance tuning tricks would also be helpful. ----- - Prashanth -- View this message in context: http://drools.46999.n3.nabble.com/Scaling-Drools-based-application-tp4026...
