My environment is Athlon 650MHz, Sun 1.3, HotSpot Client (i.e. standard
install).

With the HelloWorld test in the "jbosstest" module I get 3ms/call,
consistently.

Running the Tomcat test EAR, which does in-VM calls to a HelloWorld type
bean I get 0.08ms per invocation, i.e. 400ms for 5000 calls.
I don't know what's responsible for our differences, but the ones you
quote point to either bad environment or bad configuration (since JBoss
*can* do much better).
