Almost the same as on the forwarding performance lab.

IPSec benchmark "Equilibrium throughput" method
Once done, we start using a fast method for measuring the “IPsec equilibrium throughput” of the DUT.
From the packet generator/receiver a simple script that use netmap-pktgen will do the job:
[root@pkt-gen]~# equilibrium -4 -d 00:07:43:2e:e5:90 -t vcxl0 -r vcxl1 -l 10000 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 = 10000 Mb/s - Tolerance = 0.01 Iteration 1 - Offering load = 5000 Mb/s - Step = 2500 Mb/s - Measured forwarding rate = 1598 Mb/s - Forwared rate too low, forcing OLOAD=FWRATE and STEP=FWRATE/2 Iteration 2 - Offering load = 1598 Mb/s - Step = 799 Mb/s - Trend = decreasing - Measured forwarding rate = 1597 Mb/s Iteration 3 - Offering load = 1997 Mb/s - Step = 399 Mb/s - Trend = increasing - Measured forwarding rate = 1602 Mb/s Iteration 4 - Offering load = 1798 Mb/s - Step = 199 Mb/s - Trend = decreasing - Measured forwarding rate = 1599 Mb/s Iteration 5 - Offering load = 1699 Mb/s - Step = 99 Mb/s - Trend = decreasing - Measured forwarding rate = 1600 Mb/s Iteration 6 - Offering load = 1650 Mb/s - Step = 49 Mb/s - Trend = decreasing - Measured forwarding rate = 1603 Mb/s Iteration 7 - Offering load = 1626 Mb/s - Step = 24 Mb/s - Trend = decreasing - Measured forwarding rate = 1604 Mb/s Estimated Equilibrium Ethernet throughput= 1604 Mb/s (maximum value seen: 1604 Mb/s)
⇒ We reach about 1.604Gb/s to encrypt 5000 flows.
