If you're IO bound, you might be better off storing a few dozen lines in a scalar and printing just once every few-dozen iterations instead of on every iteration.

Im confused by this comment. The only reason I can see such a strategy making a difference is that it will reduce the number of print calls. I'd be surprised if user caching is more effective than the caching that perl itself does.
