In my case, im tunning jboss and stress my app whith jmeter. I have to score 300 simultaneous access. For that, i have 2 jboss running and 1 apache (mod_cluster) doing load balancer. Analysing the results with 120 access i get But the number of connections in use, is not on top. (im using JON to monitory connections) So... i think that it shoul probably be the number of threads. Anyone can give me an advice or tips for tunning apache? I think that apache that is limiting that. What you think?
