Comment #8 on issue 1926 by address@hidden: 2.15.12 processing speed problems

Looks like the enhancement for issue 1839 caused the slowdown.
If we avoid the more complicated note-head.cc:internal_print() from 1839,
{ \override NoteHead #'stencil = #ly:clef::print
\override NoteHead #'glyph-name = #"noteheads.s2"
\override NoteHead #'stem-attachment = #'(1.0 . 0.5)
\repeat unfold 1000 <b' g' d'>4 }
then input that used to double in compilation time between versions now
takes 12 seconds on either .11 or .12.
We can apply the overrides to mozart-hrn-3.ly and also have the same compilation times (12 seconds on my Windows box) with any recent LilyPond version.
