I tried my old computer ... Pentium-M Dothan 1.86 GHz on an AOpen i915GMm-hfs 
mobo with 2 GB RAM.
One hardware update: OpenSuSE linux system installed on SSD, all the other 
parts are older than 11 years.
That old machine only needs  between 138 and 140 seconds!

The old machine takes about 5 times longer to compile your score than my fast 
PC, and more than 50% of that
is related to the increased system clock.

But: If I do a full build of lilypond, the old machine takes about 23 times as 
long as the modern computer ;-)

Some further comments: With some slight modifications you could compile Agnus, 
Credo, etc as individual scores
and combine the pdf using a program like pdftk. That reduced the time to build 
the pdf to a bit less than 8 seconds
on the modern hardware.
