Hey Chris, I'm expecting 5000 simultaneous users, with a physical load balancer to two physical app servers. So ~2500 per machine, each running an instance of tomcat not fronted by httpd or any proxy server. (i.e., using Tomcat to serve a few static assets along with the webapp).
"are you just interested in speculative performance tuning?" That's correct - with just one user (myself) testing it everything is wonderful. I've just got that uneasy feeling the servers will explode when we flip over from our old host/codebase and get all the traffic.
