Re: Do we need to do Garbage collection when using the POI

Perhaps the most damning thing about POI-via-RPG is that even after
fighting through all the setup issues and finagling with memory
allocation, you *still* don't get very impressive performance. So
you've got almost the worst of all worlds: more complicated setup,
more complicated coding, poor-to-lackluster performance. The *one*
thing you get with POI-via-RPG is that you don't have to learn another
language. (Yes, I understand that can be a big one, but it's still a
little sad.)

We actually get much better performance out of the SXSSF streaming model
available in POI. There used to be an almost logarithmic performance hit as
the spreadsheet size grew. With streaming, it looks more linear, probably
because of the much reduced load on heap memory management.

There are still reasons to use RPG, since we're not just creating a
spreadsheet, so I don't consider it sad.
