It depends on your system and if we were forced to guess, our guess would be very loose. Fortunately you do have a running system with real queries: Make a copy on two similar machines (you will probably need more hardware anyway) and simulate growing traffic, measuring response times at appropriate points: 200 users, 500, 1000, 2000 etc. If you are very lucky, your current system scales all the way. If not, you should have enough data to make an educated guess of the amount of machines you need. You should have at least 3 measuring point to extrapolate from as scaling is not always linear. - Toke Eskildsen, State and University Library, Denmark
