After upgrading to v1.2.4 on my Deco X60 3 node mesh I thought I would dive in and try the VPN Client utilising the OpenVPN connecting to NordVPN. 
 

However I am getting extremely high ping and slow speeds when connected to the VPN. My normal 70mbps connection drops down to 15mbps when connected. I am aware to expect a drop however a drop this much makes it unusable. 
 

Connecting to the same NordVPN server using their app only drops the connection speed by a couple of mbps.
