Getting heap size full with JRFileVirtualizer

[tuspatil1]

Hi Team,

We are using jasperreports-6.20.1 community edidtion.
We are doing the performance testing of three virtualizers at our side with 10+ concurrent executions. We observed that the report on the "x" amount of a large dataset is getting generated successfully with JRGzipVirtualizer , but the same report on the same dataset is failing with JRFileVirtualizer. As per our logs, heap size is getting highly utilized by JRFileVirtualizer.

Can you please help us to understand if this is observed at the Jaspersoft side as well, that JRFileVirtualizer utilizes more heap size than JRGzipVirtualizer? Or can you please suggest, if there is any way to optimize the heap size utilization for JRFileVirtualizer?

Thanks,
Tushar

No, we haven't seen a case in which JRFileVirtualizer uses more heap than JRGzipVirtualizer.

Please attach a self contained test case to reproduce what you're seeing on our side.
