speed problems

No.  On my Windows Vista box, for a fairly complex piece of music (Finale  
Act I of The Gondoliers - about 500 bars, 30-odd pages), I get:

2.12.3 - 545 seconds
2.15.9 - 205 sec
2.15.10 - 210 sec
2.15.12 - 335 sec (+60%)
2.15.13 - 341 sec

So we see that for complex music, the problem remains.  My experience of  
running the regtests was that for simple music, 2.15.12 was OK to better;  
for longer music much worse.  I'd suggest using the Mozart Horn regtest as  
a test case/comparator that somewhat fulfills this requirement.
