The latest device I've added to this assemblage is a virtual machine

provisioned under OpenStack. It has 4 ThunderX cores (2 Ghz armv8)

subdivided off of 96-core machine. What I notice is slow network

performance through the Wireguard interface - 200 ms round trip VPN ping

times to a machine in the same data center, compared to 1 ms when

I don't go through the VPN, and only 45 ms when I use a different

machine in the same data center to an even slower Raspberry Pi 2 in my attic.

I don't claim to be an OpenStack expert, and I know there is some

considerable complexity hiding in its network stack that might not

be visible within the VM that I'm running. 

I guess the question is, what's the best way to start to make sense of

network performance within Wireguard (and if anyone knows the answer,

also within OpenStack?!). 

thanks
