There are different docker overlay network options. Developer need select. This post is to run benchmark so as to provide some information when people make decision. Note that this test is running on my laptop, and we will run more tests on UCS to further compare the result.

Purpose of the test:

Test environment:

  • topology: 2 VM on macbook pro. run docker container at each VM.
  • tool: iperf3
  • duration: 3 minutes

Test result:

Conclusion:

  • host to host has the best performance
  • container to container performance is almost equal to host to host
  • performance of docker host network is the best
  • performance of calico is the best among weave, flannel.
  • performance of flannel udp mode is the worst
