===== Using IPSec bench "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@R1]~# equilibrium -4 -u -d 00:08:a2:09:33:da -t igb1 -r igb2
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 = 499 Mb/s
Iteration 2
- Offering load = 750 Mb/s
- Step = 250 Mb/s
- Trend = increasing
- Measured forwarding rate = 670 Mb/s
Iteration 3
- Offering load = 625 Mb/s
- Step = 125 Mb/s
- Trend = decreasing
- Measured forwarding rate = 624 Mb/s
Iteration 4
- Offering load = 687 Mb/s
- Step = 62 Mb/s
- Trend = increasing
- Measured forwarding rate = 672 Mb/s
Iteration 5
- Offering load = 656 Mb/s
- Step = 31 Mb/s
- Trend = decreasing
- Measured forwarding rate = 655 Mb/s
Iteration 6
- Offering load = 671 Mb/s
- Step = 15 Mb/s
- Trend = increasing
- Measured forwarding rate = 670 Mb/s
Iteration 7
- Offering load = 678 Mb/s
- Step = 7 Mb/s
- Trend = increasing
- Measured forwarding rate = 670 Mb/s
Estimated Equilibrium Ethernet throughput= 670 Mb/s (maximum value seen: 672 Mb/s)
Using AES-GCM-128 and aesni kernel module loaded on the NetGate RCC-VE 4860, we can estimate an IPSec Equilibrium throughput of about 672Mb/s.
