Re: gEDA-user: PCB is extremely slow

[Stephen Meier <smeier@xxxxxxxxxxxxxxxxxxx>]

This type of problem needs some sort of profiling. Amount of time 
drawing each layer, amount of time drawing all polygons, amount of time 
drawing lines, arcs etc.

Of course it gets better by not having to draw the polygons unless there 
are none ;) But how much better? is it the predominent issue? or is it 
some fractional improvement?
