Could you do a reproducable speedtest while connected to the server?
Oh I found a speedtest.py on the Github.
I will test the VPN connection (tomorrow I hope)
But this my speed without OpenVPN
Code
/storage$ python speedtest.py
Retrieving speedtest.net configuration...
Testing from Ziggo (xxx.xx.xxx.xxx)... (I've hide the IP)
Retrieving speedtest.net server list...
Selecting best server based on ping...
