It's possible that this is falling back to using normal TCP sockets. Can you run the rstream test program to verify that you can get faster than 5 Gbps? rstream without any options will use rsockets directly. If you use the -T s option, it will use standard TCP sockets. You can use LD_PRELOAD with -T s to verify that the preload brings your per performance to the same level as using rsockets directly. - 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
