NAT taking 100% (single thread) CPU

Following up from ​this thread.

let's see how much of the questions there, I can answer.

Attached are the port forward rules as a screenshot.

ip r on the host should give the routing, right?

default via 192.168.0.1 dev eth0  proto static  metric 100 
10.10.10.0/24 dev vboxnet1  proto kernel  scope link  metric 100 
192.168.0.0/24 dev eth0  proto kernel  scope link  metric 100

and ip r on the guest should give the routing on the guest:

default via 10.0.2.2 dev eth0  metric 100 
10.0.2.0/24 dev eth0  proto kernel  scope link  src 10.0.2.15 
10.10.10.0/24 dev eth1  proto kernel  scope link  src 10.10.10.10

Does this answer your questions?
