Do you have a source on this? Reason I ask is because any recent documentation I've come across indicates that polling is recommended to reduce chances of livelock on a running system.
This depends a *ton* of what NIC you are using. Polling IMO should not be enabled on modern NICs. They use MSI-X to distribute interrupts to each core through the PCI bus to the APIC. As well as various methods to reduce the number of interrupts generated per second. This polling thing only worked well 10years ago. (Or if you still have 10 year old gear) -Gabe
