I recently installed an app called Dr Cleaner which frees up RAM when you quit a program. When I have quit the AirVPN client, it always says that it has freed from about 1.8GB - 5GB that the client was using. I don't understand how the client can use up this much RAM when it's purpose is solely to create a VPN tunnel.
Is the Dr Cleaner software reporting erroneously or does the client actually need to take up this many resources?
I am going to try Tunnelblik and see if it reports similar things when using.
