Re: Speed of HSSF

Intuitively, that does strike me as the most likely bottleneck.

If we could either write the spreadsheet in pure RPG as he
is, or in pure Java, I think the performance would be much better.

I can easily agree with that, but I will go a step further and say
that I suspect that a pure-RPG solution is going to be much faster
than a pure-Java solution on the i. (Not crazy-faster like the 60x
Scott is experiencing versus XSSF, but as a wild guess, I'd say around
twice as fast.)
