You're infinitely better off using Xpra instead. Not only is the UI using orders of magnitude more data, but it's expecting to animate it with a local GPU, which doesn't get forwarded! Today, running modern GTK or KDE apps over a forwarded X session is really not an option. Also, apps were being built to run on servers and have their display on your workstation, so developers were actually considering the X protocol bandwidth.

Back then we didn't have huge truecolour bitmaps, 100MB fonts, client-side rendered widgets, etc. This was fine in the 90's when X protocol was lightweight.
