I've used 4 benchmarking tests: a) \repeat unfold xx c''4; b) \repeat unfold 500 { c''4 c' \f c''' g } (this gives the skylining code something to do, which the simple one in a) doesn't); c) the Finale to Act I of the Mikado, which I created as code about 3 years ago, and runs to 496 bars and up to 30 voices and d) The full score for the Mikado, about 150 pages but set as a number (about 20) of separate \score blocks. The main problem I've got is laying the results out in a text-only email, so I've attached them as a little image.
Summary: 2.12 was very slow and unreliable on large scores. 2.14, 2.16 and 2.17.26 are similar: it look like current devel is slower where there's a lot of interleaving of notes and dynamics to be done, which is probably to be expected with the more sophisticated skylining code. I'd conclude there is no fundamental performance problem with our current build.
