Errr.. really? I use KDE4 daily and push it hard, including high end gaming and I've yet to bog it (KDE 4.13) down in any way. I had performance issues with older releases, but not for quite a while now.
One thing I frequently experience is my system becoming unresponsive to mouse and keyboard for a few minutes. That problem the reason I upgraded my motherboard to one with an Intel core i7 CPU, that's 4 cores & hyperthreading. The problem still occurs, though not as severe as my old mom board. When it happens, kswapd0 seems to be the culprit, but Firefox or Seamonkey might be involved. I run top, iotop and the System Monitor, on their own desktop to see what happens. On the new motherboard, System Monitor shows 2 or 3 cores (of 8) pegged at 100%. Incidentally, it may take a couple of minutes to switch to the desktop where I have the monitors running. I did not experience this prior to KDE4.
I've seen the same -- that kswapd0 issue, and its owned by root and I see its parent ID=2 so that "k' means 'kernel' not 'kde') -- and the load average goes up to the 20s or 30s! Now I'm running KDE 4.13 it doesn't seem to happen any more. Back when it did I tried 'by elimination'. Eliminating Thunderbird and Firefox ensured it never happened. But that was then this is now, and KDE, T'Bird and FF have all seen upgrades so I don't know .... It hasn't happened recently. Perhaps the moral is to keep your s/w up to date :-) Really though, T'Bird and FF are Gnomic/Gtk apps rather than Kde/Qt apps. I know that shouldn't have anything to do with it, but sometimes I wonder ... If LXDE, XFCE and the other lightweight DMs would handle FF start-up properly ... I run FF with multiple windows and while they all start OK with KDE with XFCE only one of them comes up. That is, I have multiple FF windows in KDE, log off, and when I log on again in XFCE and start FF again it restores all my tabs ... But only in one window. That is the tabs of one of the windows; the tabs in the other windows are lost. -- Life's a bitch. Then you die. Then you get re-incarnated and it starts all over again only worse.
