      Notes

      • Localnet / OVS is in general slower than linux bridge
      • Bridge binding is introducing additional hops
      • Reported results:
        • OCP CoreOS
          rtt min/avg/max/mdev = 0.095/0.236/4.941/0.476 ms
        • OCP-VM (localnet connection)
          rtt min/aug/max/mdev = 0.283/0.703/3.944/0.425 ms
        • OCP-VM (Linux Bridge connection)
          rtt min/avg/max/mdev = 0.182/0.576/1.028/0.187 ms
