Ways to reduce memory and cpu usage


Recommended Posts

Hi all,


I'm new the jasper reports. I'm currently developing a web reporting module using struts2,apache and jasper report.


I found a few things :


1) The CPU(dual core) usage is always 50% or more - when generating reports - large or small size

2) The memory usage will shoot up by 100MB++ or more and then it just stays there without dropping at all.


So my question is what are the available methods to reduce the CPU and memory usage further?





PS : I had already implemented swap file and use my own custom datasource. In addition,I have tested on a simple application for generating report with dummy data; it also shows 50% of CPU usage. Every time I finish generating reports, I do clear the swap file.
