LXD macvlan vs bridge performance

Host Ubuntu 18.04
which option to share containers via LXD id better in terms of performance
macvlan or bridge ?


There are some old benchmarks (Linux 3.14) that compare bridge and macvlan when used in KVM, https://events.static.linuxfound.org/sites/events/files/slides/LinuxConJapan2014_makita_0.pdf
I think that an educated guess is that you get noticeable throughput difference when you go well over 1GbE.
In addition, macvlan should have much lower CPU usage than bridge.

noticeable lower CPU??

The paper says 25% lower CPU load, when on 10GbE and under netperf (more intensive workload than standard stuff?).
