My prior post did some tests on docker overlay network performance. docker overlay network performance comparison - intel driver. After that, I receive many feedback. Two of them are

Contiv network plugin has two modes: vxlan and vlan. VLAN mode has better performance, but guest machine require vlan access. I'm using virtual box, this link shows a way to enable it Advanced Virtualbox and Vagrant tips for VLAN,PXE and Hostonly networking. Thus I have to redo all tests with virtio driver. Below is the test result, and diagrams.

  • VM to VM, host mode, mapping mode still have better performance
  • Contiv vlan mode has better performance comparing with all tested overlay network option.
  • Flannel host-gw mode has better performance than vxlan and udp mode.
  • Flannel vxlan mode performance becomes worse in virtio driver than intel driver.

I'll post a separate one to give the result on cisco UCS server.
