Hi Jeff,

I had 62 sec when transferring 211MB under load balancing mode using two ethernet ports!!!

This was bizzare so I checked again and found out that my switch and the SNAP server had AUTO NEGOTIATE set for speed and duplex mode. Common issue and screws up lot of things. So manully set the Ethernet to 100Mbps at FULL duplex and the result was pretty much in the order as before 25 sec (+/- 1sec error). So load balancing didn't really improve the performance.

I did further testing like pulling the 2nd port while file was transferring and it continued to transfer seamlessly without interruption and again at 25-26sec transfer time.

So result - not much difference in improving the transfer rate but now I have redundancy. There is another option for failover which I assume allows you to use single IP Address and failover to the 2nd port.

While for the Load balancing you to specify IP addresses for each port.
And Yes, it does truly load balance, the two ports flicker like christmas tree!!!
