I haven't had much success and/or advantages with a active/active bond, and used active/passive instead. One of the reasons for that is the app I used at a time only did one network connection worth of traffic, which doesn't gain any speed benefits from active/active. I don't recall seeing such drastic speed issues with active/active, but granted it's been a bit since I last worked with it and Infiniband in general. -Gennadiy -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
