Hi Nicolas,

         Thanks for your reply. Please find the details below.

Xms 48000 and Xmx 48000

I have not configured te MaxMetaSpaceSize and gc type. Would you please explain how can I add these flags?

There are no heap dump created as the tomcat service is getting terminated by the "kill" command sometime with flag 3 and sometime with 9

Hi Nicolas,

    I used G1GC garbage collector and it is working fine now from the memory point of view. Thanks a ton for your suggestions it helped me a lot. I used VisualVM to check the memory usage and it helped me a lot.

Regarding processing file, we are using a batch approach and reading files in chunks of one million. This then parsed and inserted to the working memory. This works fine and have a better performance than compared to 5.x.

I have one more question for you. I have a simple rule which is given below.

rule "Add to learning category from Loan Performance facts"

salience 1590

    when

        lp : LoanPerformance(lid : loanIdentifier)

        la : LoanAcquisitionRecord(loanIdentifier == lid, src : source)

then

        String status = getLoanStatus(lp);

        String [] data = src.split("\\|",src.length());

        String [] sample = new String[]{

            data[1],data[2], data[3],

            data[4],data[5],data[6],

            data[8],data[9], data[10],

            data[11],getRangeValue(data[12]),data[13],

            data[14],data[15],data[16],

            data[17],data[18],data[19],

            data[20],data[21],data[22],

            data[23],data[24],           

            lp.getServiceName(),lp.getCurrentInterestRate().toString(),

            lp.getCurrentActualUPB().toString(),lp.getLoanAge().toString(),

            String.valueOf(lp.getAdjusterRemainingMonthToMaturity()),

            lp.getMetropolitanStatArea(),status};

            BayesianService.addSample("loan_performance",sample,false);

This rule was taking roughly one minute to execute one million times when we were using 5.x and now with 6.x it is taking 3 minutes and 30 seconds. Will you be able to help me out in this?

Thanks a lot for your help and prompt reply.

Hi Nicolas,

      I think I found out the issue. During my earlier run I noticed that the time taken for GC was very high. I am now fine tuning the JVM performance and now the time for rule firing is coming down.

Thanks for your suggestions and help. It was very useful and helpful.
