-===== Basic configuration and tuning =====+===== Configuration and tuning =====
  
-==== Disabling Ethernet flow-control ===+[[https://github.com/ocochard/netbenches/tree/master/Atom_C2558_4Cores-Intel_i350/forwarding-pf-ipfw/configs|Configuration repository]]
  
-First, disable Ethernet flow-control: 
-<code> 
-echo "dev.igb.2.fc=0" >> /etc/sysctl.conf 
-echo "dev.igb.3.fc=0" >> /etc/sysctl.conf 
-service sysctl restart 
-</code> 
  
-====Enabling Tx abdicate (iflib drivers) === +===== Results =====
- +
-Second, if NIC drivers is iflib based you should enable TX abdicate (automatically done with BSDRP but not on a generic FreeBSD): +
-<code> +
-cat <<EOF >> /etc/sysctl.conf +
-# Enabling Tx abdicate +
-dev.igb.0.iflib.tx_abdicate=+
-dev.igb.1.iflib.tx_abdicate=+
-dev.igb.2.iflib.tx_abdicate=+
-dev.igb.3.iflib.tx_abdicate=1 +
-dev.igb.4.iflib.tx_abdicate=1 +
-dev.igb.5.iflib.tx_abdicate=1 +
-EOF +
-service sysctl restart +
-</code> +
- +
-==== Disabling ICMP redirect === +
- +
-ICMP redirect is enabled by default on a generic FreeBSD (it's disabled by default on BSDRP), and this feature disable the fast tryforward code path. +
- +
-<code> +
-cat <<EOF >> /etc/sysctl.conf +
-# Enabling fastforwarding by disabling ICMP redirect +
-net.inet.ip.redirect=0 +
-net.inet6.ip6.redirect=0 +
-EOF +
-service sysctl restart +
-</code> +
-==== IP Configuration ====  +
- +
-Configure IP addresses, static ARP entries and static routes. +
- +
-A router [[Documentation:Technical docs:Performance|should not use LRO and TSO]]. BSDRP disable by default using a RC script (disablelrotso_enable="YES" in /etc/rc.conf.misc). +
- +
-<code> +

-===== forwarding rate ===== +

-We start the first test by starting one packet generator at gigabit line-rate (1.488Mpps) the pkt-gen receiver output: +

- +
-It's able to forward at about about 1.12 Mpps. +
- +
-===== Firewalls impact ===== +
- +
-This test will generate 2000 different flows by using a mix of 20 different sources IP and 100 different destination IP. +

-===== Netmap performance ===== +

-Intel NIC drivers are netmap ready… what's about the rate with the netmap's packet generator/receiver ? +
