--- Comment #2 from bjoernv at arcor.de ---
Missing DBUS on remote apps is probably not the only reason for slow remote KDE
apps. 

I managed the following to prevent warnings and errors and to increase the
speed of remote KDE apps:
- X11 forwarding without SSH, but with $DISPLAY and Xauth
- starting Dbus, Console-Kit and notification-daemon daemons on the remote site
during shell login:
  e.g. with dbus-launch ck-launch-session sh -c "/usr/lib/notification-daemon;
bash"
- starting PULSE_AUDIO forwarding
  e.g. with export PULSE_SERVER=client-pc

But in summary I found, that same KDE apps run normal and others are very slow.

Examples:
Normal: Kwrite, Dolphin, Kaffeine
Slow, Xorg CPU intensive: Kate, Amarok

It's difficult to debug and to find causes for slowness of each KDE app.
Probably tools like Wireshark, Ltrace and Strace can help. Slow apps show a lot
of traffic (function calls, network traffic), but this is very low-level
information. Unfortunately the application developers are probably not very
interested in tuning their apps for remote X11 use.
