> I am seeing performance regression when using rules with 'matches' and 'not matches' (comparing 5.4.0.CR1 and 5.3.0.Final). In my case the difference is up to 100 % (2000 ms vs 4000 ms). The DRL file contains 100 rules and in the test 500000 non-matching facts are inserted into knowledge session. See the attached standalone maven project.
