I can confirm that KDE is getting slower and slower, also with a
relative fast machine, though not as fast as yours. I haven't
experienced the hangs that would need a complete reboot, but I had
freezes in 3.3.2 and sid. Now working with the alioth packages and a
sid before the gcc-4 transition works, but still could be optimized a
lot.

I suspect the lack of cooperations between KDE and fontconfig to be the
origin of the issue. Mostly, delays were cost by some app waiting for
some font before falling back to some other value. I haven't managed to
fix the issue so far. If you use russian truetype fonts, it seems to be
even more error prone.

Best,

Rigo

Have you tried to run 'fc-cache -f' as root?

Yes, but no effect. I will now try to cut down my fonts to the absolute
minimum. It was funny that on a new install it booted much faster and
then I installed something that made it slower (probably more fonts),
but as it was in a big chunk of packets to install, I couldn't
determine the exact cause.

This is not ready for a bug-report but I already had some contacts with
fontconfig maintainers on fixed-font issues and they blamed KDE

Overall it works, but there might be space for optimizations, that's
all.

Best,

Rigo

I've enabled dma in hdparamd and it's greatly improoved the performance, sono
more bluedeath effect, but some slowdowns still appear and I also think this
is about fonts or something similar.
