JSreports performance improvement in report rendering



  • Hi,

    I am trying to render reports for around 4MB data. I have followed your other links in forums and blogs on how to improve the performance and incorporated them in config file(which is attached here). Still I donot see the performance improvement. Can you please help me in getting good performance.
    Some of the resources I referred to are:
    https://jsreport.net/learn/phantom-pdf and
    https://forum.jsreport.net/topic/388/how-to-maximize-the-performance-with-multi-core-cpu/2
    https://forum.jsreport.net/topic/262/concurrent-requests/2: As mentioned here I am using strategy:phantom-server and numberofworkers=8

    https://jsreport.net/blog/pdf-reporting-performance and
    https://jsreport.net/learn/configuration
    As mentioned here I am using, this templating engine configuration:
    "templatingEngines": {
    "strategy": "http-server",
    "numberOfWorkers": 8
    }
    Have taken numberOFWorkers to 8, ie., 2 workers per CPU

    Thank you



  • I have 4 cores... that is why took 2 workers per Core/CPU
