Re: lilypond slowness?

Ok, I did some further testing ...

Test setup:
install versions one at a time to C:\lilypond and issue c:\lilypond\usr\bin\lilypond.exe -V file.ly twice and see if it halts at Building font database both times

2.6.5 seemed to work properly
didn't find anything 2.7 at (http://download.linuxaudio.org/lilypond/binaries/mingw/)
2.8.0-1 exhibits the same behavior ( i.e. is buggy)

This thread http://www.mail-archive.com/address@hidden/msg10945.html seems to talk about the same behavior..
I can also provide a FC_DEBUG=255 log if need be, but as the log file is 17.5MB ! I would need to know what to look for in order for me to find something useful from it..

anything more you would need to solve this issue?

regards,

Simon


ps. what funky business is the uninstaller up to, given that it seems to be a magnitude slower to uninstall the files than install them ?

Unfortunately, I don't have a vista machine handy to test this.

Can you check if older versions (2.7, 2.8, 2.9, 2.10, etc.) exhibit
the same behavior?  If no, can you use bisection to figure out which
version introduced the slowness?
