With the default fontconfig install, fc-cache tries to put the caches
in /var/cache/fontconfig and ~/.fontconfig. Check you can write and
create files in those directories. If fontconfig is in use at the time
of running font-cache, it has to do some locking of the cache files.
It may be more successful if you run fc-cache while nothing using
fontconfig is running (eg, shut down X and run from a command window).
The --really-force and --verbose options to fc-cache might give more
clues. Or maybe you should look for stale lockfiles or something in
those directories, or you could just try blowing those directories
away completely (rm -rf) and starting over.

Some problem with the fonts cache would certainly explain slow startup
of xft apps.
