I've noticed this one-time startup delay as well on Windows (7 and 8) and
found that it got triggered anytime I changed the contents of the system
font folder (C:\Windows\Fonts), whether adding or deleting a file. At the
next time of compiling a LilyPond file, a new font-cache database would be
created in "C:\Users\[MYUSERNAME]\.lilypond-fonts.cache-2" (note the
initial period in the directory name). If I clear the contents of this
folder, the initial delay comes up again to create a new database file. I
suspect that this directory can be found across OSs in a similar location
in the user's main directory, but I haven't confirmed this.

HTH,
Abraham
