PHREAK is slower than ReteOO with accumulate and exists ------------------------------------------------------- Key: DROOLS-1387 URL: https://issues.jboss.org/browse/DROOLS-1387 Project: Drools Issue Type: Enhancement Components: core engine Affects Versions: 6.5.0.Final Reporter: Toshiya Kobayashi Assignee: Mario Fusco Labels: support Attachments: brms-perf-comarison.zip 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 {noformat} mvn -P BRMS640GA clean test {noformat} The example output: {noformat} Running org.mk300.brms.perf.Phreak_Accumulate 2016-12-27 16:51:40,280 INFO (main) [RuleBase] ##################### RuleBase start 2016-12-27 16:51:42,322 INFO (main) [KieRepositoryImpl] KieModule was added: MemoryKieModule[releaseId=org.default:artifact:1.0.0-SNAPSHOT] 2016-12-27 16:51:42,519 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 0 tx/sec 2016-12-27 16:51:43,529 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 29,020 tx/sec 2016-12-27 16:51:44,533 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 159,216 tx/sec 2016-12-27 16:51:45,539 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 203,391 tx/sec 2016-12-27 16:51:46,539 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 202,453 tx/sec 2016-12-27 16:51:47,553 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 204,160 tx/sec 2016-12-27 16:51:48,555 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 199,914 tx/sec 2016-12-27 16:51:49,556 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 193,496 tx/sec 2016-12-27 16:51:50,557 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 200,377 tx/sec 2016-12-27 16:51:51,557 INFO (pool-1-thread-1) [PerfCounter] Phreak_Accumulate : 202,060 tx/sec 2016-12-27 16:51:52,522 INFO (main) [RuleBase] ##################### disposeAll end Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 12.394 sec -
