KDE4 has worse graphical performance than KDE3, that is know.
It is because bad drivers…
But what I’m experiencing is general bad responsiveness (a lot disk
activity, like if swapping is going on). After some usage everything
slows down to a crawl!
My machine is:
Athlon 64 2800+
1.5 GB ram
~500GB of disks
Nvidia 7600GT or Radeon 9250
For e.g. opening dolphin → disk activity raises a lot
opening ktorrent → disk activity, opening opera → disk
activity.
Cold starts are long, but warm are nothing shorter. Under KDE3 there
isn’t that much disk activity. What could be the reason in first place
for that?
Opening a movie from ktorrent → it needs seconds before it starts
to play!
And even worse, closing mplayer will lead to a black screen and disk
activity will raise again (really seems like it is swapping, but free
shows nothing).
In KDE3 movie opens in under a second, without disk trashing around
that much and closing it it’s like nothing ever happened, desktop is
super responsive.
What could be the problem of that?
I like a lot KDE4 but this makes me really think about using it ever
again.
UPDATE: It was ktorrent, lowering speed helped.
However in kde4 always when moving larger files starts to show above
simptoms, meanwile kde3 is unaffected.
I’m also using kde 4.2rc1 from factory and do not experience said
problems. You may want to make sure that KDE4 Desktop Search and Akonadi
are disabled, other than that I don’t know what’s going on with your
system. The only irritating problem I experience here is with the
grouping of icons in the taskbar where they change the black background
color, see pic below
