One trick which improved performance from what you describe to ok for
me, was rerunning fc-cache - I had a directory of fonts in my home
directory, and it seemed to parse them every time something started.
At some point in FC5 development, a fontconfig update seems to have
been rather buggy, and caused performance problems also. I don't
know the details, but the package maintainer and others have alluded
to this, and runtime behaviour was certainly suggestive of it as well.
Upon Matthias' request (fontconfig maintainer), I have removed the
fc-cache call from the xfs initscript, which should improve system
boot time, as it no longer mandatorily calls fc-cache. We're now
relying on font rpm packages to invoke fc-cache directly from %post
and %postun instead. While this is not directly related to the
thread, part of the reason for the removal, is that I'm told that
if fonts.cache-* files are not present, fc-cache will get ran
automatically at runtime to generate them, but on a per-user
basis instead of systemwide. That's useful for user ~/.fonts
directories if it works, but it sounds like it doesn't work from
what you're saying.
If that's the case, it's likely to be a fontconfig bug IMHO.
