Thanks Aron Looks like these are the ones you are mentioning. https://sourceforge.net/p/jett/tickets/77/ https://sourceforge.net/p/jett/tickets/78/

Thanks Aron

Thanks Aron Can you give me one of these ticket numbers? I searched through tickets created by you but did not find any performance related ones which were fixed after 0.9. I am already using 0.9.1 so those fixes should already be there.

Thanks Etienne for the pointer and explanation. We confirmed from heap that apache POI is generating lots of objects and they are taking a significant heap space. So this should be the problem..

We are facing GC overhead limit exceeded while doing ExcelTransformer::transform on bean map. Our JVM heap size is 8GB and unfortunately increasing it is not an option. I am trying to find correlation between bean map size and memory footprint taken by JETT. Is there one? If I can have a correlation e.g. JETT takes 2X memory than the bean size. I should be able to circumvent the problem by killing the report generation. I looked at the existing topics but did not find information anywhere about this....
