How many stories can NarraFirma handle?

Because the stories (and answers to questions) are text only (so far), NarraFirma is able to handle quite a few. We have stress tested it with more than 10,000 stories, and it worked fine, though slowly. With larger numbers of stories you will see slower performance (depending on what sort of computer it is running on). But with typical projects of 100-300 stories, and even several hundred stories, you should not see a problem.
