Then, probably nobody cares > of my complaints, so dont worry. Eric, do not get it soo personally :) After all it is only a matter of how we enjoy the process and have fun with the development. Really, I appreciate your work and help, and likely this misunderstanding happened because of a bad mix of the original bug and this performance implication. Original bug has really nothing with what we discuss here. And while the performance problem with bound sockets creation may be visible, I did not observe it, while the idea implemented with this approach shows up clearly in the graph I posted. So I vote by both hands to further improve it by moving things around so that there would be no unneded cache flushes during update of this field. -- Evgeniy Polyakov -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
