Under 2.11.42 the fonts are cached in C:\Documents and
Settings\[username]\.lilypond-fonts.cache-2. This also
contains 2 small and one large (682 KB) files, but when
LilyPond compiles it changes just the large file - every
time. This is pretty certainly where the extra time is
going, as the time stamp on this file updates around 45 secs
after starting the compile.
This may well be the same as the Vista slowness problem
which was also related to font caching.
Yes, I encountered the same problem on XP; it seems to re-calculate
the font cache on every compilation, and therefore takes ages to
compile anything. However, I didn't report it since I assumed I was
doing something wrong.
