 +===== Using IPSec bench "Equilibrium throughput" method =====
 +
 +Once done, we start using a fast method for measuring the "IPsec equilibrium throughput" of the DUT.
 +
 +Notice that the reference device (IBM x3550-M3) used in front of the Netgate has a [[IPSec performance lab of an IBM System x3550 M3 with Intel 82580|equilibrium throughput of 843Mb/s]]. Then if the value measured during this bench is close to 843Mb/s we had to found a more powerful reference device.
 +
 +From the packet generator/receiver a simple script that use netmap-pktgen will do the job:
 +<code>
 +[root@R1]~# equilibrium -u -4 -d 00:08:a2:09:33:da -t igb2 -r igb3
 +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 = 0.01
 +Iteration 1
 +  - Offering load = 500 Mb/s
 +  - Step = 250 Mb/s
 +  - Measured forwarding rate = 399 Mb/s
 +Iteration 2
 +  - Offering load = 250 Mb/s
 +  - Step = 250 Mb/s
 +  - Trend = decreasing
 +  - Measured forwarding rate = 250 Mb/s
 +Iteration 3
 +  - Offering load = 375 Mb/s
 +  - Step = 125 Mb/s
 +  - Trend = increasing
 +  - Measured forwarding rate = 375 Mb/s
 +Iteration 4
 +  - Offering load = 437 Mb/s
 +  - Step = 62 Mb/s
 +  - Trend = increasing
 +  - Measured forwarding rate = 399 Mb/s
 +Iteration 5
 +  - Offering load = 406 Mb/s
 +  - Step = 31 Mb/s
 +  - Trend = decreasing
 +  - Measured forwarding rate = 399 Mb/s
 +Iteration 6
 +  - Offering load = 391 Mb/s
 +  - Step = 15 Mb/s
 +  - Trend = decreasing
 +  - Measured forwarding rate = 391 Mb/s
 +Iteration 7
 +  - Offering load = 398 Mb/s
 +  - Step = 7 Mb/s
 +  - Trend = increasing
 +  - Measured forwarding rate = 398 Mb/s
 +Estimated Equilibrium Ethernet throughput= 398 Mb/s (maximum value seen: 399 Mb/s)
 +</code>
 +
 +Using AES-GCM-128 and aesni kernel module loaded on the NetGate RCC-VE 4860, we can estimate an IPSec Equilibrium throughput of about 400Mb/s.
