We recently upgrade our Drools Expert from 5.1 to 5.3, expecting big performance gain. But from the tests we done so far, the result is mixed at best. Is this common or there is sth we can fine-tune the system? All time is in milliseconds. Thanks

In Drools 5.2 the only performance work was for lazy truth maintenance

5.3 brought some improvements for MVEL integration, particularly compilation. But it would offer only minor improvements.

This is all covered in the release notes:
