Compiling files with lots of data

[Mike Solomon]

Hey lilypond users,
    I am compiling a file w/ many notes (on the order of 5*(3^7) 32nd notes
including spaces) that, @ the "interpreting music" stage, counted up to
2184.  I started it last night and it has been running for upwards of 9h
using version 2.13.0 on a 1.5 GHz PowerPC running OS X 10.4.11 .  I am
wondering if there are any steps I can take (short of just putting less dots
on the page) to speed up the process?  Attached is the file (sorry that it
is not a minimal example - by its nature, it is maximal, although you'll see
very quickly that the vast majority of it is similar).
    There are a few things in it that I suspect may be causing the problem,
so my question would be: for any one of these things, will its inclusion
make lily run slower when she is processing large amounts of data?

1)  I have set timing = ##f instead of using cadenzaOn
2)  I have removed the Bar_engraver.
3)  I have set the Stem stencil to ##f instead of removing the
Stem_engraver.

Additionally, if there are any other optimization suggestions you have,
please let me know!

Cheers,
~Mike
