Well, Scott has given you some good pointers on how to make a fast system. However, your original question ("is this fast enough") is impossible to answer, especially if the users are allowed to run absolutely anything they want. I bet you I could craft a query that takes more than 30 seconds regardless of how fast you make your system. Having said that, I'll add the suggestion that you should put as much RAM in the box as possible. It can only help. As others have said, if you only have four users, then CPU power isn't going to be such a problem, and given that, I'd disagree with Andrew and say as long as you have plenty of RAM, Java can play well with a database on the same box. Depends what it is doing, of course. Matthew -- To be or not to be -- Shakespeare To do is to be -- Nietzsche To be is to do -- Sartre Do be do be do -- Sinatra
