 +====== OpenVPN performance lab of an IBM System x3550 M3 with Intel 82580 ======
 +{{description>​OPenVPN performance lab of a quad cores Xeon 2.13GHz and quad-port gigabit Intel 82580}}
 +===== Hardware detail =====
 +
 +This lab will test an [[IBM System x3550 M3]] with **quad** cores (Intel Xeon L5630 2.13GHz, hyper-threading disabled) and a quad NIC 82580 connected to the PCI-Express Bus.
 +
 +This CPU includes AES-NI: AES-CBC,​AES-XTS,​AES-GCM,​AES-ICM.
 +===== Method used =====
 +
 +The benchmarking method used here is detailed in [[documentation:​examples:​Setting up a VPN (IPSec, GRE, etc...) performance benchmark lab]] and [[documentation/​examples/​gre_ipsec_and_openvpn#​openvpn|OpenVPN example lab]].

 +===== Equilibrium throughput benchmark methodology =====
 +
 +Once done, we start using a fast method for measuring the "​equilibrium throughput"​ of the DUT.
 +
 +From the packet generator/​receiver a simple script that use netmap-pktgen will do the job:
 +<​code>​
 +[root@R1]/​tmp#​ equilibrium -u -d 00:​1b:​21:​d3:​8f:​3e -t igb2 -r igb3 -o 0.001
 +Benchmark tool using equilibrium throughput method
 +- Benchmark mode: Bandwitdh (bps) for VPN gateway
 +- UDP load = 500B, IPv4 packet size=528B, Ethernet frame size=542B
 +- Link rate = 1000 Mb/s
 +- Tolerance = 0.001
 +Iteration 1
 +  - Offering load = 500 Mb/s
 +  - Step = 250 Mb/s
 +  - Measured forwarding rate = 500 Mb/s
 +Iteration 2
 +  - Offering load = 750 Mb/s
 +  - Step = 250 Mb/s
 +  - Trend = increasing
 +  - Measured forwarding rate = 539 Mb/s
 +Iteration 3
 +  - Offering load = 625 Mb/s
 +  - Step = 125 Mb/s
 +  - Trend = decreasing
 +  - Measured forwarding rate = 543 Mb/s
 +Iteration 4
 +  - Offering load = 563 Mb/s
 +  - Step = 62 Mb/s
 +  - Trend = decreasing
 +  - Measured forwarding rate = 545 Mb/s
 +Iteration 5
 +  - Offering load = 532 Mb/s
 +  - Step = 31 Mb/s
 +  - Trend = decreasing
 +  - Measured forwarding rate = 532 Mb/s
 +Iteration 6
 +  - Offering load = 547 Mb/s
 +  - Step = 15 Mb/s
 +  - Trend = increasing
 +  - Measured forwarding rate = 545 Mb/s
 +Iteration 7
 +  - Offering load = 540 Mb/s
 +  - Step = 7 Mb/s
 +  - Trend = decreasing
 +  - Measured forwarding rate = 540 Mb/s
 +Iteration 8
 +  - Offering load = 543 Mb/s
 +  - Step = 3 Mb/s
 +  - Trend = increasing
 +  - Measured forwarding rate = 543 Mb/s
 +Iteration 9
 +  - Offering load = 544 Mb/s
 +  - Step = 1 Mb/s
 +  - Trend = increasing
 +  - Measured forwarding rate = 543 Mb/s
 +Estimated Equilibrium Ethernet throughput= 543 Mb/s (maximum value seen: 545 Mb/s)
 +</​code>​
 +
 +=> OpenVPN (userspace) reach about 454Mb/s which is about half IPSec performance (kernel space)
