Found some time today... I tested a huge ly-score, once sent by Jean-Charles for testing different guile-versions: https://lists.gnu.org/archive/html/lilypond-user/2016-11/msg00948.html Thanks again! I made it compilable with recent ly-master out of 55ca32d951dd17556df8d0332b861f0cd189379a (though I didn't fix all warnings and programming errors) Tested with these guile versions: guile-1.8.8 from tarball guile-2-2-6 out of a69b567d97f7c9193924c775e1dd86e43a35b8bd guile-3.0.6 from master, i.e. out of 85433fc2b122dc78342c3c83941949d1d9318399 (although (version) says: 3.0.5.116-85433) There are some guile-warnings, multiple instances of: WARNING: (#{ g478}#): `smallCaps-markup' imported from both (lily) and (#{ g171}#) WARNING: (scm framework-ps): imported module (lily) overrides core binding `_' The latter one is about gettext and PITA. I compiled Urtext.ly from the tarball linked above (giving a 158 pages pdf): %%%%%%%%%%%%%%%%%%%% guile-1.8.8 real 4m37,304s user 4m14,144s sys 0m7,717s %%%%%%%%%%%%%%%%%%%% guile-2.2.6, (version) says: 2.2.6.7-9a11b real 7m18,995s user 6m41,808s sys 0m11,960s eating much more memory than guile-1.8.8 %%%%%%%%%%%%%%%%%%%% guile-3.0.6, (version) says: 3.0.5.116-85433 real 5m49,587s user 5m11,033s sys 0m9,488s eating a little more memory than with guile-1.8.8 but far less than guile-2.2.6 %%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%% Interestingly I found some older timing values from former tests: %%%%%%%%%%%%%%%%%%%% released lilypond-2.19.52 with guile-1.8.7 real 8m16.191s user 6m39.864s sys 0m10.860s %%%%%%%%%%%%%%%%%%%% with guile-versions from 2.0.14 and 2.1.7 I noted: Best result was: real 25m17.082s user 31m1.668s sys 0m5.480s Worst result was: real 77m44.348s user 100m40.324s sys 0m18.932s Though, my noted former results are a little messy: I can't say anymore which guile-version with which lilypond-patches was best/worst. Anyway, both, LilyPond and guile seem to have improved a lot. Cheers, Harm
