Thanks James, It's an honor get answered by you, I'm a big fan of you projects (activemq and servicemix) I'm using both right now on production (servicemix is a very tiny small project, but we're very happy within it ;) )
:)
Just one final question, if you don't mind, you said it runs in a single VM, but would mind sharing the info about the server? Is it dual? We are planning to run in a dual Xeon 2.8Ghz 8gb RAM, on a first stage, later we're gonna need a cluster, with 3 machines like that (thanks for activecluster :P )
Those numbers (10,000-14,000 concurrent Ajax clients per JVM) were achived on a dual opteron box (about $3K) using Sun's Java 5 JVM with CPU load at about 40%. James
