Export JasperReports to DOCX causes performance issue

we are generating docx report through aspose, it is taking lot of time (20 mins) when large amount of data to be printed(14000 records). The memory foot print of aspose is going beyond 1GB. please anyone can suggest if we can reduce this time by any aspose or jasper configuration. or any alternate approach to handle this situation.
steps we are following
1- get the required data from DB
2- fill report with jasper report
3- export to docx (issue is here with memory and taking time)
4- postprocess on report data
With less number of records it works fine and generates report withing few seconds.
