Do you need to use udlfb? Your fastest option on a CPU-limited system
will probably be to use as few software layers as possible between you
and the hardware. I suggest using libdlo and libjpeg to do everything
in user-space. I posted some code to do this for SVG here:
http://lists.freedesktop.org/archives/libdlo/2009-May/000060.html - you
could do something similar using libjpeg.
(How large are your jpegs? Are you scaling them, or anything like that?)
