We've found and fixed a few dumb problems (like reinit'ing Xft on every instantiation of a font) and there's definitely some redundant repainting going on, but as far as I can tell Xft is just inherently slow anyway. That may be the price of client-side rendering. The Xrender extension is supposed to cache the glyphs, but on some X servers (notably the Darwinports version of X.org that I use) Xrender is disabled, and I've had reports that the caching doesn't seem to work anyway. This may be due to more problems like those already fixed, but unfortunately the Xft and fontconfig documentation doesn't tell you anything about those aspects of wire protocol semantics. Information to the contrary, especially how to get XEmacs to do it correctly, would be *very* welcome.
