FreeBSD is tuned to handle WAN connections, with decent LAN performance. If you know you're going to be doing exclusively low latency / high bandwidth connections, such as you see with a typical NAS device, you can make a few changes that will sacrifice WAN performance and increase LAN performance.
One change you can make that will not harm LAN performance, and has a good chance of increasing it, is to disable nagle's algorithm.
In FreeNAS this can be done by adding a sysctl, under the system menu.
The variable is net.inet.tcp.delayed_ack and the value is 0.
