   I just want to know what the maximum performance of OpenBSD networking currently is (and what hardware configuration to achieve it) and if asking that means I'm "trolling" the OpenBSD community I think that is probably a sign that they need to do some self-reflection

     @feld How many bits per second does an OpenBSD machine dropped out of an airplane get? :blobfoxthinkgoogly:

     @feld You got me interested. I wonder what's the maximum throughput on their virtio drivers. My guess isn't much (maybe 5Gb) since a fast performing system was never OpenBSD goal. Paranoid levels of security is.

     @phnt and the funny part is you get more paranoid security with HardenedBSD which is based on FreeBSD and so then you also get... performance!

     @feld It's around 6-7Gb/s. Better than I expected, but there seems to be some CPU utilization bug, because no matter how many threads I throw at it, all virtual CPUs will stay ~20% in the idle state. pf does not seem to make an impact after the first few runs have half the throughput for whatever reason. MTU also makes no difference, but that's probably because it's virtio.
