Since JBoss uses Tomcat, it can use any of the standard connectors
available for it (basically HTTP(s) and/or AJP).

Huh? I thought you were instrumenting your code within Tomcat resulting
in 4ms transaction times, and you now wanted to know how much overhead
was being added (on top of that) to the transaction by the other
components. Is that not the case?

Actually, if your transactions are taking 4ms and you can shave off 1ms,
then that's a 25% performance improvement. If your transactions are
taking 300ms, perhaps 1ms isn't that big of a deal.
