OpenVPN speed

[BiTRiP]

Hello,

I'm currently running OPNsense 18.7.9-amd64 and configured a static OpenVPN connection to my vpn provider, CyberGhost.
Unfortunately, I noticed that the speed via OPNSense is much worse than using their client straight on my desktop.

Using their client I can max out my speed of 200Mbit/s. Doing the same thing via OPNSense by downloading from the same source, I get only 80Mbit.
The OPNSense machine is not doing much, just 10-11% cpu usage while downloading.

Any ideas to solve this?

Thanks.
