[ovs-dev] [PATCH ovn 21/21] tutorial: Add benchmarking test script to run within sandbox.

Ben Pfaff blp at ovn.org
Sat Mar 27 00:31:47 UTC 2021


This is originally from Numan Siddique.  I have adapted it a bit
to run faster by using the ovn-nbctl and ovn-sbctl daemons and
combining multiple calls into just one.

I'm uncertain whether to actually commit this; I need a sign-off
from Numan to do so.
