Hi Paolo,
can't say anything to 1) or 2)
ad 3)
LilyPond still uses guile-1.8, if you observe some speedup, then
because of some optimisations.
Experimental builds with guile-2 showed a huge slow down, the last
time I tried it out, which is admittedly a while back.
Though, there is continuous hard work to improve the situation. I
should try it out again...
The suggestion to focus on guile-3 makes no sense at the moment,
because it is not broadly in the distros, afaict.
Cheers,
Harm
