Re: GtkTreeView - why so SLOW?

["S. Eken" <eken bfw-online de>]

Hi Olaf,
as I already posted under the subjects "Strange behaviour of
scrollbars in GTK 2.0" and "GTK 2.0 5 times slower than 1.2" in
gtk-devel-list I experienced a dramatic decrease in performace and a
similar increase in CPU usage, BUT (!!!) the CPU time is eaten up by the X
server (which, in my case is on a different (slower) machine as the one
running the application).

It would very interesting to know if your application uses the 60% CPU
time or if it is also the X server. Er, that is if you ARE using a
system with X.
