works fine over my wifi which is considerably less than gigabit speeds
then again I only run applications remotely that are sensible to run 
remotely such as text editors (geany) & file managers (thunar)
I cant see any reason why I would want to run a web browser remotely

I can see that even this would be too slow on some connections but it 
invariably works better that Remote desktop which seems to be the 
preferred approach in the windows world where they don't have much choice.
