Ouch! Sometimes it takes up to 20 seconds on my 750Mhz, and sometimes
it runs in ~0.7 s.
I think that it's highly sensitive to the fonts.conf file, but I don't
yet know where it's screwing everything.
For instance, mozilla-xft seems to not have this problem... I've just
copied the fonts.conf that I use for mozilla to the fonts.conf that I
use for abiword and I will see if the problems goes away.
Anyway I will start tracking it

It needs to do that, but only once. The first time that the first xft
app starts.
But it should not scan the whole file system, but just the dirs listed
in fonts.conf and its subdirs (what dirs do you have in your
fonts.conf?). The problem is that in my computer the scan happens a bit
too much (not everytime, but sometimes).

Yes, absolutely. Even the "fast" case (the 0.7s) is almost
inacceptable, let alone the "worst" case...

Ok, that should be my fault. I will try loading big files and start
caching things... I have some ideas of where this problem comes...

Yes, and partially. I'm pretty sure that the low speed loading
documents is my fault. For the low speed starting you should have to
blame Keith, but I will try to at least to find the bottleneck and
report it.
