Clearly, you have never waited one minute for a full screen update from a 
machine half around the planet.

That is what happens here with hextile + an compressed SSH tunnel, just in 
case you thought this was pure speculation.

It is pretty obvious why, too: generic compression, such as SSH's, will 
never outperform specialized compression, such as tight compression.
