Might have to do with the tunnel? If much of the traffic is going through a tunnel, that's probably all hashed to the same rx queue and could overwhelm a less capable cpu?
I've always had good experiences with the Intel x520/x540 10G nics on FreeBSD though, and given the eBay pricing, there's been no reason for me to explore any other offerings. Sadly, my recently installed fiber internet is 1G only, but maybe one day they'll update; but I can't really test if my system can do 10G without a proper upstream.
