Hmmm... perhaps I was testing something more full-fledged (though not
a server application) that could be used as a skeleton for a
command-line tool. I'll have to check. I'm not seeing it be that
fast on my current machine, but is less that 1 second with Java
6--though this machine is rather powerful.
Still, it's not going to be that fast on a 400MHz ARM. :-)
