This makes a huge difference, although its still an issue to a degree because Solaris has way more fonts than any Linux distro I've ever seen. /etc/fonts/fonts.conf on a RH 9 install just has <dir>/usr/share/fonts</dir> <dir>/usr/X11R6/lib/X11/fonts/Type1</dir> <dir>/usr/X11R6/lib/X11/fonts/OTF</dir> <dir>~/.fonts</dir> whereas on Solaris 10 with gnome 2.6 the same file lists 48 directories! And many of those have a significant number of fonts and quite large fonts.dir files. Imagine trawling through that ever time you start an app. If you build the cache it doesn't need to do so remotely so much work, but it still trawls the directories to check the cache files although I'm not 100% sure of the precise difference. And I doubt you have exactly this in the blastwave build but you get the idea. So there is something of a scaleability problem with fontconfig and there was some recent discussion on this list on ignoring BDF files and using enums instead of strcmp which long term could mitigate this, but I doubt its that easy right now. You could look at your fonts.conf (and perhaps local.conf) and decide if you really need all of those, but be careful unless you REALLY understand what you are doing. -phil.
