Ok, then i suppose we can conclude it is a bug on e1000 (holds tx_lock on tx side and adapter queue lock on rx). Adding that lock will certainly bring down the performance numbers on a send/recv profile. The bizare thing is things run just fine even under the heavy tx/rx traffic i was testing under. I guess i didnt hit hard enough. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
