Does your database > backend support so many > client connections? Data transfer : There will probably be small data transfers on the order of tens or hundreds of bytes more or less continuously. Parallel Connections : thirty or forty probably at the lowest end, as many as passable at the highest end. I realize that range is vague, I am pretty sure that if the number of connections is very high then I will inevitably have to go to a multiple server approach. My goal in this case is to delay that as long as possible. Efficiency is a goal in and of itself as well. Database Client Connections : I plan to implement connection pooling for the databases so I should never really have more then a handful of open connections the database depending on how many concurrent users there. __________________________________________________ Do You Yahoo!?
