As much ram as you want. No syscalls. Must exhibit a load curve similar to: y | ............... | . |. +----------------x Where x == requests per second sent to the machine and y is the number of resposes per second sent out of the machine. Hint: read the phttpd and /dev/poll papers for an idea of the breakdown that happens for larger values of x (make the cpu slower to cause the interesting points to move lower). For a third dimension to the graph, make the number of total connections the z axis. Ok, TUX can do it. Now list for me some server that really matters other than web and ftp? If you say databases, then I agree with you but I will also reiterate how the people who need that level of database performance is "nook and cranny". I think there is nothing wrong with doing a TUX module for situations where 1) the server is important for enough people and 2) scaling to the levels you are talking about is a real issue for that service. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
