Hi all, I have a rule that looks like below: Rule "CheckSomeConditionRule" When $project:Project(status==STATUS_ENUM.DATA_FETCHED) $rule:Rule(name=="CheckSomeConditionRule") $processResult1:ProcessResult(projectId==$project.id, inputSource memberOf $rule.inputTableList                      , outputTable=="") $processResult2:ProcessResult(projectId==$project.id, inputSource memberOf $rule.inputTableList                      inputSource!=$processResult1.inputSource, this!=$processresult1, outputTable=="") $processData1:ProcessData(parent==$processResult1) $processData2:ProcessData(this!=$processData1,parent==$processResult2 ,eval($processData2.getValue("a").equalsIgnoreCase($processData1.getValue("a"))) ,eval($processData2.getValue("b").equalsIgnoreCase($processData1.getValue("b"))) Then     /////do important stuff here end I am trying to run this rule with two data set (represented by ProcessResult class that holds several rows in terms of ProcessData objects), each data set has 10000 records only. (In real usages, we will have atleast a million records in both these data sets.) I am inserting all of the rows i.e all rows represented in terms of ProcessData objects. I am inserting some 20000+ objects to test this. While inserting, first 10000 records are getting inserted fairly quickly, the next 10000 records are taking a lot of time.. in tunes of 15 -30 mins. I understand that drools is trying to create activations as i insert facts but this seems to be too slow. is it eval in my conditions that is making it slower? or is it equalsIgnoreCase method? if i use == instead of equalsIgnoreCase my rule never gets fired. I am doing something wrong? please advice. My data structure is inherently hierarchical:  ProcessResult (represnts a table)     contains        ProcessData (represents rows)           contains              list of Dimensions & list of Metrics (accessed via getValue() method above) Thanks in Advance, Ravi -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Strange-Performance-P...

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?

Thomas, For testing purposes, i am inserting only 5 rules, 2 ProcessResult Objects and 20000 ProcessData Objects.

When i use a rule that does not use hardcoded "table1", it inserts first 10000 ProcessData objects fairly quickly, for next 10000 it is taking forever. Like in 30 mins its able to insert say 1000 or so objects. :-( -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Strange-Performance-P...
