FreeNAS usage part1

For a quick test I used Veeam Zip 7.0.x to backup my VM's to the FreeNAS.  Electricity usage spiked at 71 watts, at rest the server consumes a mere 61 watts.  It looks as though we are getting 30~40Mbps sustained transfer rates, Veeam showed spikes up to 70Mbps.  Currently, assuming I am reading the graphs right it is not CPU or ram bound, that being said perhaps I will switch to ZFS.  Also I don't have LACP/RoundRobin, or any sort of load balancing between the NICs on the FreeNAS. I have ESXi set up to use RoundRobin on two NICs.
