    Description

      PHREAK is slower than ReteOO in case of:
      1. with accumulate
      2. with exists

      Attached test case brms-perf-comarison.zip contains 4 tests to compare the performance:

      ReteOO_Accumulate vs Phreak_Accumulate
      -> ReteOO is 30% faster than PHREAK in average

      ReteOO_Exists vs Phreak_Exists
      -> ReteOO is 30% faster than PHREAK in average

      You can run the test with

      mvn -P BRMS640GA clean test

      The example output:

      NOTE: These tests run in different JVMs (reuseForks = false in pom.xml) so the order of test execution doesn't affect the performance.

          is incorporated by

          Enhancement - An enhancement or refactoring of existing functionality RHDM-180 PHREAK is slower than ReteOO with accumulate and exists

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
