Thanks for sending that project! I find it very instructive to review 
completed work by experienced users. My computer here is one I built in 
July 2012 or so. I guess it's not exactly newish anymore, was nothing 
extra high-end to begin with, and currently it should have a reformat 
and re-install.

Intel DZ77SL-50K mainboard
Intel Core i5-3450 "Ivy Bridge" 3.10 GHz CPU
24 GB RAM
Windows 7 Pro SP1 64-bit
LilyPond 2.19.46, Frescobaldi 2.17.2.

MSDM.ly and its entourage compiled in 1 min 4 secs.

As others noted, a program like LilyPond only uses 1 CPU core. So fewer, 
faster cores could quite possibly outperform a higher-end processor with 
more, slower cores. In my case, with this project LilyPond promptly 
sends CPU usage to 25% and stays there until finished - it's maxing out 
1 of the i5's 4 cores. So have 6 or 8 or however-many more cores would 
probably not help here.
