Forwarding performance lab of a quad core Intel Atom C2558E (2.40GHz) with 2+4 Gigabit Intel NIC
This lab will test a Netgate RCC-VE 4860 (dmesg):

This device use 2 kinds of Intel NIC:
The generator MUST generate lot's of IP flows (multiple source/destination IP addresses and/or UDP src/dst port) and minimum packet size (for generating maximum packet rate) with one of these commands:
Multiple source/destination IP addresses (don't forget to precise UDP port to use for avoiding using number 0 filtered by pf):
pkt-gen -i igb2 -f tx -n 80000000 -l 60 -d 198.19.10.1:2000-198.19.10.20 -D 00:08:a2:09:33:da -s 198.18.10.1:2000-198.18.10.100 -S 00:1b:21:c4:95:7a -w 4 -U
And the same with IPv6 flows (minimum frame size of 62 for having a correct empty UDP packet):
pkt-gen -f tx -i igb2 -n 1000000000 -l 62 -6 -d "[2001:2:0:8001::1]-[2001:2:0:8001::64]" -D 00:08:a2:09:33:da -s "[2001:2:0:1::1]-[2001:2:0:1::14]" -S 00:1b:21:c4:95:7a -w 4 -U
Receiver will use these commands:
pkt-gen -i igb3 -f rx -w 4
