When I do a sh interface on a switch or router, one of the lines reads output flow-control is XON, input flow-control is XON. Does anyone know of a reason you would want to turn this off? I actually thought that flow control is really decided/controlled by the end hosts, not the network devices. I work for a company where low latency is critical. If I turn off flow control, would that improve latency because I wouldn't be slowing traffic down?
Any incite on this would be greatly appreciated.
