Implemented Multithreading using run base batch , but batch run time is not decreasing !! help

(1) ShareShare
ReportReport
Posted on by Sachin Mittal 490

I have implemented multithreading using run base batch framework but when I run it, it gets multiple tasks, but batch run time did not decreased (tested same logic without multithreading in both cases time is same) I am adding my code, please help with what I have done wrong , added code in reply section

time takeen , 2 minutes for my business logic without multithreading

after implementing multithreading and below code time was same, it should reduce because I have added 10 run time tasks.

    yes, I understand that, but I have implemented my same logic using sysoperation framework, that is working absolutely fine (multiple tasks gets created, also batch time reduced to 12 sec from 3 minutes , adding Sc too ) I don't understand why run base is not working

    Assuming that threads are created correctly. One factor that can affect the performance of your batch job is the number of threads . Sometimes, your batch job tasks may have to wait for other batch jobs that are running at the same time, which can make it take longer to finish. To test this, you can try disabling other batch jobs and see if your batch job runs faster. When you configure your batch job in the Production environment, you can also use the Priority based scheduling option to reduce the waiting time for your batch job tasks.

    This seems to be a duplicate of your other thread, How implement multi-threading using SysOperation framework. There you also talked about 25 fields, which is useless information, and told us nothing about what actions you run in parallel.
     
    Starting the same discussion again from scratch is a waste of time. Instead, you need to give us better information.

    If you use multithreading in a wrong way, you may indeed get no benefit or even worse performance (because of an overhead).

    for demonstration purposes (to implement multithreading), in demobusinesslogic class, I have added 25 fields in sales table of type string, assigned some values to all these fields. 
    so running batch job will fill values in all 25 fields.

    Hi Sachin,
     
    Can you tell what exactly the batch job should do? When using multiple threads, depending on the circumstances, it won't be faster. If you have a few records to process, a single thread could be faster. In case there are locks on several tables, the multi-thread might make things worse. 
     
    Using a single or multiple threads should be part of the design with a careful decision. I would suggest using the Trace parser tool to find out what exact coding or database calls are causing a delay. Then you can find out what to improve. We don't know what exactly is being executed in your DemoBusinessLogic class.
