Lilypond can't work while you are working: since input and processing are going
on in separate programs, Lilypond has to do all the processing while you wait
and stare at your desktop background. A system that integrates data entry and
graphical output in the same program can do some of the work "behind the
scenes", while you're still writing the latter parts of the file. But Lilypond
is designed differently, so its score layout machinery isn't even running while
you're working on a file.
For longer files, you can reduce your wait by only processing the part you're
currently working on; see "Skipping corrected music" in the manual (section
10.5 in the manual for version 2.10).
The first file you (successfully) process on any computer will take even longer
because the first time Lilypond runs it prepares the fonts it will use. This
should only happen once; later runs will be faster because they use the cached
font information which was generated that first time.

I can't really help you with Schenker graphs -- never used one, can't read
them. Note however that Lilypond is NOT good at Schenkerian graphs. In fact,
Lilypond doesn't do Schenker at all. But Lilypond is good at Plain Old
Notation, and P.O.N. can be hammered into Schenker graphs by overriding
Lilypond's ideas about e.g. what noteheads to use, where to put beams, whether
to print stems etc.
This is what Kris Shaffer did and wrote about in that article two years ago. In
his opinion, twisting Lilypond's arm until it produces Schenker is easier (or
at least more straightforward) than trying the same with any graphical music
typesetter which, like Lilypond, is made for Plain Old Notation and doesn't
know about Schenkerian analysis.
In other words, you can't write a Lilypond input file that describes a Schenker
graph and have that processed into a graphical file. You have to write a file
that describes the "ordinary" notation, then add in all the ways in which the
Schenker graph differs from that.
This is why the first replies to your questions about Schenker graphs said
little more than "learn to do ordinary notation first" -- Schenker is not a
function of the software, it's an advanced step you can take once you are at
least slightly familiar with the software.
Hope this clarifies a thing or two. With solstice-related greetings
