loop

So, I'm playing with a couple of QLogic QLA2340s connected directly together. I've got options here to either have them act as a loop, or in point to point mode.

What's the difference if I'm only going to have two machines connected together? Is point-to-point more efficient? The firmware has an option to prefer loop, then fall back to p2p.

Anyone have any idea if there are performance benefits or drawbacks? It's pretty hard to find that information.

Ok so from all my research I'm fairly positive P2P is not possible in Silverlight 4 (in browser).
