>             Project: Drools
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: drools-core  (expert)
>    Affects Versions: 5.2.0.M2
>            Reporter: Roman Novak

>
> 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  )
>        )
