What errors exactly are you talking about I did not notice any error messages
in your logs.

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 ...
