i wish there was more time in the day so we could merge the performance branch due to the memory savings.

Hi karl, that does work, but I am actually looking for a better way of doing it programatically, so that I don't have to hold on to this huge data in memory and write it at the end. I cud do a chunk write, close and open the file, then append the next chunk, but I don't want to get into that...that will just make it slower.

Hi Pillai.
Increase the JavaVM via e.g. -Xmx256m (applicable for Tomcat and Eclipse - there main() specific; on different platforms maybe a bit different).

I am experiencing "out of memory" issue with POI. I am doing an export operation and dealing with huge data. And I think maybe it has got to do with the large number of HSSFCells being created. Right now I do a single workbook.write() at the end of the operation. Is there a way I could do the write in chunks or any other ideas to improve the performance. Has anybody else experienced these issues before.
