BalanceNG Benchmark Results

This is our collection of BalanceNG Benchmark results using the default benchmark parameters (a packetsize of 1514, a window size of 16 and a duration of 300 seconds).

The BalanceNG benchmark is intended to measure the maximum performance which a platform is able to deliver (with all it's components: Operating system, interfaces and switches). Actually, load balancing itself is not measured by this and happens on top of the basic "switching engine" of BalanceNG.

For more information see the benchmark command in the BalanceNG manual.

How to obtain BalanceNG platform benchmark results

Step 1: Network and interfaces connection setup

Connect two physical interfaces of the machine to the same switch. Two separate interfaces are required for the BalanceNG "benchmark" command.

Step 2: Download and install BalanceNG

Download BalanceNG from the BalanceNG download URL. The "bng" executable may be directly executed from the directory created by extracting the compressed distribution archive. On Solaris systems the "bngfilt" STREAMS module needs to be installed, take a look at the README file in the bngfilt-binaries directory of the distribution. Note: A reboot of the operating system is not necessary.

Step 3: Attaching the interfaces and starting the benchmark

Attach the interfaces and start the benchmark like this (Licensing not required, replace "eth0" and "eth1" by your interface names and don't forget to load the "benchmark" module):

    # ./bng start
    BalanceNG: starting up ...
    # ./bng control
    BalanceNG: connected to PID 7895
    bng# module benchmark
    bng# interface eth0
    interface eth0 successfully attached
    bng# interface eth1
    interface eth1 successfully attached
    bng# benchmark eth0 eth1
    bng# show benchmark
      benchmark active and running:
        duration (seconds) : 300
        packetsize         : 1514
        window size        : 16
        packets sent       : 397266
        packets received   : 397250
        seconds remaining  : 289

Step 4: Display the benchmark results after 5 minutes execution time

    bng# show benchmark
      benchmark finished with the following results:
        duration (seconds) : 300
        packetsize         : 1514
        window size        : 16
        packets sent       : 10463134
        packets received   : 10463118
        lost packets       : 0
        packets per second : 34877
        bytes per second   : 52803869
