                                 daemon.run('ip a') :   8.973ms
Running 'ip netns exec bench_ns ip a':
                   sudo ip netns exec bench_ns ip a : 162.098ms
     sudo rootwrap conf ip netns exec bench_ns ip a : 268.115ms
          daemon.run('ip netns exec bench_ns ip a') : 129.876ms

So it looks like running daemon is actually faster than running "sudo".

That's pretty good! However I fear that the extremely simplistic filter
rule file you fed on the benchmark is affecting numbers. Could you post
results from a realistic setup (like same command, but with all the
filter files normally found on a devstack host ?)

Thanks,



That's a good point to have a fair comparison to the c translated one,
I ran it with all the rootwrap filters provided in havana, but I will
rerun the benchmark if that changed.

Anyway, I don't think there should be a huge difference, the worst
part was the startup part.
