You can't set the maximum number of threads for a host, only for a connector (which must be attached to a service, not a host). I don't see any 1s timeouts that you have configured in HAproxy. That's why I was wondering what is being configured on the Tomcat side (specifically, the keep-alive timeout). If you have 10000 connections from HAProxy ( x 3 ) then each Tomcat server should have 30000 connections available. The number of threads is not important unless you are really using a significant number of those 30000 connections simultaneously, or if you are using the BIO connector (which requires one thread for each connection). > I have managed to get some configuration via jConsole.
