We are in fact suggesting some ideas that address the current stack issues along the way. Witness the discussion we had about the tcp_ack() costs wrt. pruning the retransmit queue and tagging packets for SACK, I'm working on a new data structure and layout to cure all that stuff. But I think we can do better. Jamal said to me one email, "If even only half of Van's numbers are real, this is really exciting." Rusty and Alexey are looking at the problem from another direction. Go back to the unified flow cache, implement all the hair to do that, and then we can look at netchannels because they will be so much more straight forward at that point. - 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
