RE: Performance when using POI to create an excel workbook.

I'll tell you what. If you all are REALLY interested in the answer to this
question, you need to get Don Denoncourt (DDenoncourt@xxxxxxxxxxxxxx)
involved in this discussion. He's the only person I have ever known who can
consistently get sub-second response out of ANY java application, regardless
of where it's running.
