What is the real performance of flannel #738
We are deploying openshift platform and I have some simple investigation on flannel.
Below is my procedures:
From our test results I have seen 99.5% performance compared to native host network.
However, I searched google and most people say the performance is 50% approximately.
Did I do something wrong in this test ? Or the flannel auto leverage the aws overlay network infrustructure that accelerating the vxlan ?
Just to confirm @tomdee , I performed this benchmark:
So 23.4GBytes Total data transfered in 30 secs with average 6.68Gbit/sec bandwidth.
So 11.1GBytes Total data transfered in 30 secs with average 3.17Gbit/sec bandwidth.
