Hi, I'd like to note that this performance problem seems still to exist in OFED 1.3rc1. On our testing environment (2 Hosts, Xeon 3040, Mellanox MT25208 HCA) with OFED 1.3rc1 on Fedora 8/Kernel 2.6.23.9-rc1, ib_rdma_bw yields a bandwidth of 658 MB/sec with a one megabyte message size. Other benchmarks show similar results.
