I haven't quantified it yet, but desktop GNOME performance seems very
sluggish. Many seconds to launch apps. Many seconds for the GNOME panel
menu to drop down and populate with icons. In general the lack of
performance is bad enough to be very noticeable and annoying.

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.

I recompiled the xorg-x11-server package with this patch a couple of minutes ago:
https://bugs.freedesktop.org/show_bug.cgi?id=4320#c11

The performance increase on the desktop this bug delivers is quite dramatic.

  Dennis
