Hello, I did some tests to get an opinion about the performance of drools (5.0.1).
At one test I have a rule with 10 objects (same object-type) declared as condition and got an OutOfMemoryException. I noticed that the memory usage increases when I insert the last facts into my StatefulKnowledgeSession. On fact 7 it increases with 10MB, on fact 8 with 46MB and on fact 9 with 170MB. I debuged a little bit in the drools-source and noticed that the LeftTupleMemory increased exponential with the number of facts I inserted. My question about this behaviour: Is a condition limited to a handful of facts or do I have to change the syntax to get it working? I know that I could insert the same object-types as a list, but assume that I have 10 facts with different object-types. Thanks in reply, Christian -- View this message in context: http://n3.nabble.com/high-memory-usage-for-rules-with-more-than-6-facts-as-condition-tp718114p718114.html Sent from the Drools - User mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list [email protected] https://lists.jboss.org/mailman/listinfo/rules-users
