There are all sorts of things that can affect X11 performance which won't
on a fast connection. Fonts can be a big issue. In the early days we had
a few bitmapped
fonts. These days we have complex coloured backgrounds with scalable fonts
on the remote side, so vastly more data to be transferred just to display
text. If you have
only simple terminals and line graphics remote X11 can work well (even over
connections) , but if you want to use complex GUI's then it is more
efficient to transfer
the rasterized data than the X11 instructions to create the raster, e.g.,
Systems like Google chromebooks are already bypassing most of the X11
the windows you see on the screen are managed by the browser process which
them all into one big X11 window. Many high-end graphics apps are moving
in this direction
to be able to work directly with the GPU and go beyond the X11 RGB-based
The next logical step is a new GUI environment with X11 running as an app.
CygwinX already does this.
For me, the biggest advantage of VNC is that you can shut down the client
and then reconnect
later without disrupting the running jobs.
With VNC turning of special effects and replacing the default background
with a uniform
colormakes a big improvement in performance, even over gigabit ethernet.
With a non-uniform
background just moving or resizing a window requires moving a lot more data

There are now a number of powerful web-based "notebook" interfaces such as

these on a
chromebook with Chrome OS 41 and Google's "Freon" graphics stack. Lots of
