Comment #4 on issue 1211 by n.puttock: [PATCH]Optimizations for pure-height
approximations. (issue1817045)
http://code.google.com/p/lilypond/issues/detail?id=1211
I've done some more benchmarking, this time using Valentin's opera* (which
annoyingly, I still haven't succeeded in compiling in Ubuntu due to lack of
RAM).
*
http://repo.or.cz/w/opera_libre.git/blob/refs/heads/new:/scores/opera/main.ly,
with some tweaks to get it working in 2.13
The following timings were produced via mingw builds under Windows XP on a
dual core
Athlon X2 4800+ with 2 GB of RAM:
2.13.36:
optimized: 96m8.735s
standard: 207m49.985s
(recent) git master:
optimized: 139m50.875s
standard: 249m6.891s
Unfortunately there's been a drop in performance since 2.13.36; I've
narrowed it down to Joe's fix for issue 1240 (5266aa). As you can see from
the above timings, it adds over forty minutes to both optimized and
standard builds.
