The performance of LilyPond 2.19.18 on Windows is _much_ better than
previous versions. Some examples:
A 26 page multi-score piece I've been working on:
2.19.16: 114s to compile
2.19.18: 52s
... [etc]
That's remarkable. I can see no change between 2.19.16
and 2.19.18 that might account for this enormous change.
The only effect of this magnitude which I've seen in the
past is to do with setting up the font library when LP
is run for the first time. But that would be an increase.
Any chance your 2.19.18 is using a different hard disk,
an SSD maybe, which the others weren't?
Trevor
No. They're all installed on an SSD. It's CPU limited anyway.
I thought 2.19.16 might be quicker because of the change to the compiler,
but, as you say, have no idea why .18 is so much quicker than .16. I'm
pretty certain it's a genuine difference: I only noticed because the score I
was working on suddenly appeared more quickly!
