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...
