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. On Mon, May 20, 2013 at 2:51 PM, Eduardo Schoedler <listas@esds.com.br>wrote:

As for migration to another OS, I find FreeBSD better as a matter of
network performance. The last time I checked OpenBSD was either lacking or was in the early stages of multiple cores support.
If you do decide to go the FreeBSD route (you can run openbgpd on FreeBSD if you like), check out the POLLING option on ethernet NICs, it cuts down on the number of interrupts and can increase performance, particularly when dealing with smaller packets.
Polling on FreeBSD in modern NICs is discouraged.
