With my working copy of lilypond (on a 1.6 GHz Opteron), I have this down to 
3m22.321s. That's still about 3 times slower than 2.8 but it's progress. 
FWIW, I don't think 2.10 (and above) will ever be as fast as 2.8 when there 
are many scores -- the newer versions do a lot more work in the page-breaking 
stage and there is a limit to how much it can be optimised.

I can't reproduce this (although I'm running git head instead of 2.11.13).
