Yes, once you stop doing NAPI and demux in the driver, we start using the HW interrupt mitigation facilities again. > cpu usage on tx is a significant part of the CPU usage > issues for many interesting NFS workloads. I know SAMBA is using sendfile() (when the client has the oplock held, which basically is "always"), is NFS doing so as well? Van does have some ideas in mind for TX net channels that I touched upon briefly with him, and we'll see some more things in this area, we just need to be patient. :) - 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
