Joe, this is going to be highly dependent on your data set, layers served and usage patterns so I don't think anyone can answer this for you. We too are about to go into production with geoserver and what we did was proxy geoserver through apache httpd which amongst other things gave us access logs. We took several days of real usage from those logs and fed those to jmeter to load test. You can ramp up the number of concurrent threads and see how geoserver performs. If you are using tomcat as the container you can monitor that from within your jmeter script as well as watch it on the server. The only thing left is to translate what X simultaneous users from jmeter really means in real world usage. I have not taken the time to do analysis of time between real world queries, to get a better idea of what a "normal" single user load produces, but in my case I'm estimating 1 continuous thread is equivalent to 5 to 10 active users. I hope I'm right :) hth charles
