Since it is a full duplex switched network, there should not be any collisions happening.
I have a similar situation with a slightly larger cluster. At first I also thought it was a network performance problem. But then I ran the iftop program to watch the network in realtime and I saw that I wasn't even close to sending enough data to tax the switch. I still don't know the cause of the problem but I'm pretty sure it's not cause by excessive network traffic. I suggest you try iftop to see what your program is really doing.
