Key: JBRULES-3459
URL:
https://issues.jboss.org/browse/JBRULES-3459
Project: Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: drools-core (expert)
Affects Versions: 5.4.0.CR1
Reporter: Petr Široký
Assignee: Mark Proctor
Labels: regression
Attachments: expert-matches-perf-test.zip
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.
