Ways to reduce memory and cpu usage

[simon82]

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?

 

Thanks.

Simon

 

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.
