I only get 4 Gbps from my 10 Gbps server, I'll never ask "why" online, because I'm 100% guaranteed to get the silly answer of "enable Jumbo Frame". 10 GbE servers worked over Internet for a decade with no jumbo frames. Actually solving it requires testing a bunch of hypervisor, guest, routing, bridge, netfilters combinations to find the PPS bottleneck (conveniently worked around by jumbo frames).
