The number of fonts in your KDE desktop might be slowing it down

http://www.kdedevelopers.org/node/1654

Now the problem is that KDE doesn’t need one font, but about five (monospace, sans serif fonts in different sizes). And as QFont is per process, every KDE/Qt application does this calculation from scratch. It very much depends on your setup of course, but let’s assume we do this for 10 applications in KDE startup. So doing 50 font matches (way too few, but I’m just trying to make a point): this makes 5 Billion instructions wasted on KDE startup. Now divide this 5 by number of Ghz you have to see how many seconds you waste. So go - deinstall that fonts! 15 fonts ought to be enough for everyone
