Uh, latency in local gigabit net is a LOT lower than 5ms. > We're actually (and to think, today I trotted out that joke about what you call a group of nerds--a well, actually) talking multiple orders of magnitude through which kernel traps are being amplified. I've measured it through network as well, and the impact is smaller, but still large if you just increase the number of connections a bit.
