Hm, dragging things around might not be snappy, but it's quite fast 
here ( ~ 1/10 sec delay the first time I touch a frame)
Some other action take a very long time:
* opening or creating a new doc: the current code uses Qt's XML code 
which is just to slow.
* switching dialogs: some issue with Qt/Mac which will improve hopefully
* Typing text: Scribus' text system will be rewritten during 1.3.x and 
I'll take care that it *does*get snappy then.
Also we are on the move to replace the graphics system with cairo. 
While that will slow down things in the beginning, I hope it will give 
sped improvements in the future.

Another thing: The Scribus binary is not optimized for your system. 
This will happen automatically by OS/X when you start/restart Scribus 
several times. Did you do that?
Don't judge Scribus' speed by its first run!

That is already in.

Yes. Maybe not numerically the same, but close enough.

It's a mixture of things. Some speed enhancements just didn't make it 
in yet, current build doesn't use as much optimization as might be 
Qt/Mac isn't as optimized as Qt/X11, the Mach/Darwin/OSX system makes 
some things slow which are no problem on Linux, etc.
One think which is really abominable on OS/X is the speed of the memory 
management system. When I run  the profiler, sometimes half of the time 
is spent in malloc, destructors or free() !!

Don't worry. By the way, how does Quark or InDesign speed compare to 
their Windows / Linux versions? (hm, do they have Linux versions at
