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:
Hi Valentine,
Thanks for picking this up.
- 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?
Yes, the test result shown in the talk was started from empty to
gradually reach 20k lports on 200 lswitches.
- What is the batch size in port_create_args?
I remember it was 100. In addition, there were 5 jobs running in parallel.
+Lei to confirm.
Could you recall how long (approximately) does it take to create and
bind 20K ports with these settings? This would be really helpful.
Thanks,
Valentine
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?
