JSreports performance improvement in report rendering

virajitha.3112

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
