Would it really mess people up if netperf started doing CPU utilization
measurements by default on those platforms where it did not require
prior calibrarion? I think that might make it more likely that when
folks run tests, even over loopback (esp on MP), we'll get the service
demand figures that help show the the change in stack efficiency.

BTW, the style of the netperf test banner tells me you might want to
upgrade to a newer version of netperf :)
