Thanks for the suggestions!

Well, it looks from the outside as if the fontconfig cache is there.  
Is there a way to check that it's being used? I have 30 files in  
~/.fontconfig, one of 358KB, two 282KB, two 281KB, others ranging down  
through tens of KB to several of the smallest ones at 80B. Dates are  
yesterday and the day before!

Does anyone know of an Xft speed test application that I could use to  
see which operations are slow? (Or just another Xft-intensive  
applicatiion which I could install (ideally from macports!) ...)

On another note, I have now observed that there are a number of X  
Errors being reported in the console from which XEmacs is being run.  
Here are the last few. Could they be responsible for this slowdown?
