Since it has been fashion to complain about KDE/GNOME faults on
LinuxToday lately, I thought it would be worthwhile pointing out
that these desktop environments are not the ones that are solely at
fault. The fault could just be GNU/Linux. Waldo Bastian has put up
a nice little paper concerning the speed issue in KDE, especially
the speed of application start up and how the GNU linker is a main
bottleneck.
“In this paper I would like to bring the attention to
an important performance bottleneck in the ld.so linker on
GNU/Linux systems wrt C++ programs. I will try to offer some
suggestions for improvement and hope that this paper will lead to a
discussion in the GNU/Linux community that eventually will lead to
a solution that addresses this problem.It should also be noted that ld.so currently does a fine job for
the things it was designed. The problem is that it wasn’t designed
for todays Linux Desktop.Starting a KDE application from the command line is slow. Slow
is a very subjective term, but when it comes to a graphical user
interface, things are typically perceived as slow when there is a
latency of more than 0.3 secs. between action and reaction. So if I
click on a button, it should bring up a window on my screen within
0.3 secs. If it takes longer, users tend to perceive the system as
slow.KDE is slow. Since I am very concerned about KDE I have been
looking into the reason why KDE is slow. Obviously there are a
number of factors that contribute to the problem. What we are
interested in is the startup-performance which I would like to
define as the time it takes between the moment the binary image is
being executed and the moment the first visual feedback appears on
the screen.”
