In my introduction, I showed a few graphs from our upcoming paper, RDMA Performance in Virtual Machines using QDR InfiniBand on VMware vSphere 5 that showed we can use passthrough mode (VM DirectPath I/O) to deliver 1.75us half ping-pong latencies for Send and 3us for RDMA Read using polling completions and 7.6us using interrpt completions for RDMA Read.
