OOM issues with Spudsoft emitter when the reports contains Styles or Charts

Hi Team -

I am using Spudsoft Emitter (uk.co.spudsoft.birt.emitters.excel_0.8.0.201310230652.jar) to generate XLSX output files in a project which uses BIRT 2.6.0.

When the huge volume of data is extracted out of system, the report execution fails as it occupies entire available memory. On further investigation, I found out that enabling "ExtractMode" will improve the memory usage and the performance if the report doesnt contain any styles or charts.

Can you please let me know, if there are any solution to improve the memory consumption and performance when the reports are extracted with styles & charts using spudsoft emitter.

Please let me know if you need any additional details.

Thanks In Advance,
Naveen.
