Hi Vaughan!
I’ve included a large project if anyone with a newish computer would like to
test their compilation time. The main file is MDSM.ly. It takes my computer
between 4 and 5 minutes to compile.
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.
cu,
Knut
My system:
=========
mainboard: asus h97 pro gamer
cpu: i7-4790K, 4.00 Ghz (turbo speed: up to 4.4 GHZ,)
SSD: Samsung SSD 850 PRO 512GB
os: Linux, based on openSuSE Tumbleweed
For the test I used lilypond 2.18.2.
Compile times:
============
1st run: 27,123 seconds
2nd run: 26,697 seconds
3rd run: 26,700 seconds
4th run: 26,901 seconds
