The CPU utilization is high.. I guess SA and clamav are causing this,
but you can relatively easily move them to a separate machine.
Also the number of outgoing blocks is a little high, especially compared
to number of incoming blocks... I'm not sure what causes this, though.
I'd run a few filesystem benchmarks to find the maximum throughput - when
your utilization reaches values close to that, the load will start to
grow exponentially...
