If gprof profiling works on uClinux, try using that to find out where
most of the time is being spent in the server. Also try doing some
benchmarking to find out what types of operation are particularly in
need of improvement (drawing horizontal and vertical lines, drawing
pixmaps, moving areas around, etc.). Once you have a better idea of what
exactly would most benefit from optimisation, write versions of those
routines (blit, line drawing, palette conversion, whatever) which run
faster on your hardware.

If it doesn't work, you're not hitting it with a big enough hammer
