Intel's networking fastpath basically just throws power consumption out the window and dedicates entire cpu cores to spinning on the network devices.
100% cpu usage, constantly, but you get really low-latency networking!
A somewhat less intrusive method is to direct only the interrupts you care about to the "isolated" cpu while leaving all the rest to be handled as normal.
