I think loading the jpegs is the problem.  May be you can gain an impression
of the speed of Imlibs rendering code when having a look at

   http://www.physik.uni-halle.de/~e2od5/debian/paul.html

Loaded images of any format are displayed subsequently.  If they are all of
the same size it is a rather fast display I think.

Loaded images can be displayed much faster!

I think this doesn't matter for Imlib.

May be :)
