I don't understand why, but the GRO issue seems to be the problem that I see with low performance (0.06 Gbps transferring 4k packets in one direction). 2.6.36 and 2.6.37 work fine for me. I see problems with 2.6.38, 3.0, and 3.2. I didn't test other versions. I applied the 'fix GRO merge failure for IPoIB' patch to 2.6.38 and 3.2, and in both cases the performance improved. I'll wait for and test the final fix. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
