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 PC Engines APU2 has a 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.
root@pkt-gen # equilibrium -4 -u -d 00:0d:b9:41:ca:3d -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 = 359 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 = 356 Mb/s Iteration 4 - Offering load = 313 Mb/s - Step = 62 Mb/s - Trend = decreasing - Measured forwarding rate = 313 Mb/s Iteration 5 - Offering load = 344 Mb/s - Step = 31 Mb/s - Trend = increasing - Measured forwarding rate = 344 Mb/s Iteration 6 - Offering load = 359 Mb/s - Step = 15 Mb/s - Trend = increasing - Measured forwarding rate = 351 Mb/s Iteration 7 - Offering load = 352 Mb/s - Step = 7 Mb/s - Trend = decreasing - Measured forwarding rate = 350 Mb/s Estimated Equilibrium Ethernet throughput= 350 Mb/s (maximum value seen: 359 Mb/s)
And it reach a maximum of 359Mb/s.
