[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2982) Massive performance degradation from 5.2.0.M1 to 5.2.0.M2

Massive performance degradation from 5.2.0.M1 to 5.2.0.M2 --------------------------------------------------------- Key: JBRULES-2982 URL: https://issues.jboss.org/browse/JBRULES-2982 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core (expert) Affects Versions: 5.2.0.M2 Reporter: Roman Novak Assignee: Mark Proctor Priority: Critical the drools-planner SolutionInitializer takes 75 minutes to complete im 5.2.0.M2 5.2.0.M1 took 9,5 Minutes It also seems that accumulation queries with init, action, result sections break down completely in performance. The following query takes now 3 minutes 45 secs to complete. Before it was ~1 sec. The cardinalities: PostingPeriodOpt = 5 MediumLocationOpt = 25000 MediumBookingOpt = 13000 query "queryMediumPartlyTaken" $pp : PostingPeriodOpt() $mlo : MediumLocationOpt(mTypeId == $pp.mTypeId) $mp: MediumPeriodUsage( subOptimal > 0 ) from accumulate( $mbo : MediumBookingOpt ( mediId == $mlo.mediId, eval(timeInterval.overlaps($pp.getCycle())) ), init ( MediumPeriodUsage $mpu = new MediumPeriodUsage($mlo, $pp); ), action( $mpu.addBooking( $mbo.getIndexRange() ); ), result( $mpu ) ) end
