After some very quick testing with everything default, I am witnessing results that are far below what I would have expected. I have a few questions: - how do I identify if polling on an interface is enabled? I see no difference with ifconfig output - do I need to compile a new kernel to be able to enable/disable polling? - without moving some hardware around, I only have a single box connected to a router, and I've been testing from that box to a different interface within the router. Will the test results be optimal if I ping all the way through the router to a second device connected to it? - how are the results affected when generating and receiving the test packets within the router itself (as opposed to using outside devices)?
