Apache POI Java Excel Performance for Large Spreadsheets

Question

I have a spreadsheet I\'m trying to read with POI (I have both xls and xlsx formats), but in this case, the problem is with the xls file. My spreadsheet has about 10,000 row

Answer 1

I did some more detailed profiling and it looks like the problem is actually in code outside of POI. I just assumed this was the bottleneck, but I believe this is incorrect.
