Can anyone tell me what the 'default' hardware requirements are for JBoss-ESB? I want to prevent to advice any overkill equiment for our clients, but it still must preform well. Maybe it would be nice to know what a minimum and a optimal hardware requirement would be. In our case it would be a setup for a non-clustered ESB. The current platform we are using is JBoss-ESB 4.8 with JBoss-AS 4.2.3.
