Problem is the IP performance over the Infiniband fabric is not that great, here are some IPerf test results. The results are running the cards in connected mode, with 65520 MTU. Datagram mode was worse. Kernel tweaking done via the Mellanox docs didn't make things any faster or slower basically performance was the same either way.
