Yea but using the applet with openvpn gives me 16mbps - i even tried several servers close to me.
Doing without and using OpenVPN client I got 43mbps ...
So confused what to do
I see. It depends, I personally value Astrill applet high especially thanks to selective routing. No idea why your speeds using OpenVPN on the applet differ so much with the Merlin's / Asus version, perhaps they are tweaked.
