Performance improvement shown by x11perf not reflected in GtkPerf

[Arnaud Mouiche]

I think gtkperf is more a tool to test gtk non-regression or 
optimization (on a same X server), than a tool to test X.

I tried to use it to see if EXA optimizations that optimize everything 
by doing nothing (screen stay black), makes Gtkperf more efficient.
the result was that xorg without EXA management overhead (so without any 
optmization) gives better results than xorg with a EXA optimization that 
can't be more efficient...

Indeed, gtkperf ony creat pixmap, but doesn't try to move / blit / 
compose... all the thing a acceleration can be used for.

so what you need is a perf tool more usefull that measure the user 
experience feeling (scrolling, transparency, move, composition).

Does somebody know one ? I'm also interested.
