networkmanager vs openvpn

Hi!

I tried to connect my company’s vpn server through networkmanager (netrunner rolling, kde). First time it was failed, then i installed the networkmanager-openvpn package, which solved the problem, i could finally connect. The problem is the connection is extremely slow, even the print of the routing table (takes a minute or so).
When i connect thorugh the console (sudo openvpn --config vpn.ovpn) everything is fine.
