LilyPond evaluates all its code. In 2.0, ‘eval’ was rewritten in Scheme, which is really nice from a maintenance viewpoint, but also means that ‘eval’ is slower than 1.8’s ‘eval’, because we’re ‘eval’ itself is interpreted bytecode. In 2.2, ‘eval’ is still written in Scheme but the compiler and VM have made a lot of progress, which is why your results show performance closer to 1.8. However, you’ll get all the benefits of 2.0 and 2.2 once as much LilyPond code is pre-compiled. Do you think you could copy the .go makefilery from other projects and see how it goes? Thanks, Ludo’.
