Re: [rules-users] Strange Performance Problem in Rules

Hi Wolfgang Laun-2, i continue to have problems with performance of this rule. I made few more observations: if i write the rule like this (notice hardcoded tbale name in input source comparision), it runs fast. $project:Project(status==Status.DATA_FETCHED) $rule:Rule(name=="somerulename") $processResult1:ProcessResult(projectId == $project.projectId ,inputSource == "table1",outputTable=="" ) $processResult2:ProcessResult(projectId == $project.projectId ,inputSource == "table2" ,inputSource != $processResult1.inputSource,outputTable=="") $processData1:ProcessData(parent==$processResult1) $processData2:ProcessData(parent==$processResult2 ,eval($processData2.getValue(SomeEnum.toString()) .equals($processData1.getValue( SomeEnum.toString()))) ,eval($processData2.getValue(SomeEnum.toString()) .equals($processData1.getValue( SomeEnum.toString()))) ) Now if i write my rule like this, it becomes dead slow. $project:Project(status==Status.DATA_FETCHED) $rule:Rule(name=="somerulename") $processResult1:ProcessResult(projectId == $project.projectId ,inputSource == $rule.inputSource,outputTable=="" ) $processResult2:ProcessResult(projectId == $project.projectId ,inputSource == $rule.inputSource ,inputSource != $processResult1.inputSource,outputTable=="") $processData1:ProcessData(parent==$processResult1) $processData2:ProcessData(parent==$processResult2 ,eval($processData2.getValue(SomeEnum.toString()) .equals($processData1.getValue( SomeEnum.toString()))) ,eval($processData2.getValue(SomeEnum.toString()) .equals($processData1.getValue( SomeEnum.toString()))) ) Can anyone please help me here?
