You are running Fedora-18, right? Can you please try using either kernel 3.6.0-0.rc6.git0.1.fc18.x86_64 or an F-17 kernel, most Fedora 18 kernels have various debugging options enabled causing significant additional latencies in the network stack. Also watch top and see you're not maxing out your CPU ... Regards, Hans
