I understand that Lilypond uses the "local-eval" facility a lot for embedded Scheme. This is a facility that was indeed faster in 1.8. I would expect that 2.1.7 would be faster than 2.0, if that were the case, as 2.1.7's evaluator is faster. Hard to say, though. That interface does not get a lot of speed attention. We could take a look and see what we can do. I guess we need some profiling first. Can you run lilypond under callgrind under 1.8 and 2.1.7 and attach the generated callgrind.out.PID for each run? Run like this: valgrind --tool=3Dcallgrind --num-callers=3D20 lilypond foo.ly Thanks, Andy
