Hey Leen,

that's a nice posting - i am looking for hints like that for a while now.

I want to add that I just compiled qt 3.1.1 in /usr/local/qt-3.1.1/ with 
QTDIR=/usr/local/qt-3.1.1 and my special Pentium4 flags (-march=pentium4 -O3 
-fomit-frame-pointer) set for gcc (have to modify a file in ./mkspecs/ 
subdir). For ./configure use -thread and enable gif support (see ./configure 
--help).

Then I linked /usr/lib/qt3 to /usr/local/qt3 and made an 'ldconfig'.
On the next start of SuSE KDE 3.0.5 the system uses qt-3.1.1 optimized for my 
CPU. I don't experienced any problems - but a slight improve in performance 
(i can not measure it, just 'feeling').

This is why i do not like SuSEs rpms - they are optimized for Pentium1 but 
with backward compatibilty to x486.

The next steps should be:
 - compiling of KDE 3.1, gfx libraries and Freetype with P4 optimization 
(anything else is worth recompilng?)
- give it a try with Intels icc (should improve P4 speed up to 100% over gcc)

Who has any experiences or hints for that?

Cheers, Tim
