Also, anti-aliased fonts are rendered client side and then the full color
images (including the alpha-channel to blend with the background to produce
the anti-aliased effect) of the characters uploaded to the server to display.

I don't think gtk/gnome have any option to use the old client-side font
system anymore, though I do know Sun Ray server admins often turn off
anti-aliasing for reduced memory usage & improved performance.

In fact, the upstream Solaris JDS packages have a multi-user-desktop package
that contains a number of tuning options designed to reduce memory usage and
improve performance for Sun Ray servers - some of them may help on low-powered
single user desktops as well - you can see info about what that sets and how
on http://docs.oracle.com/cd/E23824_01/html/E26032/osdme.html
