ROCK64 as VPN Gateway

[Talkabout]

I always suggest using https://www.armbian.com/rock64/  It's definitely the gold standard as far as the Rock64 is concerned.

Yes, I have tried this distribution also. The issue here is that the main purpose for me buying the Rock64 was OpenVPN performance. Although the tests mentioned in this thread run fine the throughput is much lower than with Ubuntu Bionic (Armbian approx. 3MByte/s, Ubuntu approx. 8,4MByte/s). I was not able to figure out where the difference is. On Armbian the OpenVPN process is somehow only using 25% of CPU, on Ubuntu it is more than 50%. Is there a general limitation of CPU utilization on Armbian? Is there a way to change that?

Thanks!
