How many instances?

[dave]

Is there a limit to how many instances I can run on my Project Server
2003 box? I have ample enough hardware to handle quite a few, but
didn't know if there was some sort of "best practices" limit?

It depends more on the number of users and how often they are
accessing/updating rather than the number of instances.
Performance data about project server is hard to get ahold of. I don't think
that microsoft publishes any hard guidance.
