Hi all,
We are doing some stress testing on OVN 2.7, and wanted to reproduce
results from the talk [1]. Looking at ovn-scale-test sources, I have two
questions:
- Do I get correctly that the benchmark always starts with the empty
northbound db. Then lswitches are added, then you add ports to each lswitch?
- What is the batch size in port_create_args?
In short: is it true that for the setup involving (say) 10000 ports
spanned over 100 lswitches in the aforementioned test, a Rally task
would look like this?
