The main problem is that each time you compile a score, it builds it
from scratch: the longer your score, the longer it takes to produce an
image. (You say 1 or 2 seconds, but with longer scores, it can take
several minutes each time).

There could be some way to implement an "incremental" processing
(which could recalculate only the part of the code that has changed
since the last compilation), but currently this is not possible
(unless you have a few thousands euros to spend in it, then I guess
lots of things could become possible ;)

Yes, but RoseGarden is a MIDI sequencer, not a score editing software.
It can produce scores, but the output quality (layout, typo, printing
etc) can't be compared to LilyPond.

You can try Canorus, the evolution of NoteEdit. It's a WYSIWYG
notation software like NoteEdit, but under the hood it uses an
interesting XML-based notation code, with Contexts and Objects like in
LilyPond; besides, I heard it can easily export native LilyPond code.
I haven't really given it a try yet but it's still under active
development.
