Fastest way of generating a preview

[Nils]

Hello list,

what is the fastest way to create a lilypond preview of your file?

I expect to trade quality and correctnes for speed. 

One example, which is even in the manual I think, is to deactivate the links in 
a pdf
#(ly:set-option 'point-and-click #f)

What about the non-pdf backends? Is it faster to generate a raster image?
