Hi there,
I managed to dig up some old timings for lilypond (linked against
1.5.6), and the smallest change (the trigger in scm_malloc) actually
brought the biggest improvement:
1.5.6, lilypond on the K.V.498 piano-part, a moderately large score (heap
size: 2 M cells / 6 M malloced) is down from
* (gc-times . 128)
to cvs, newgc:
* (gc-times . 32)
The improvements in running time seem to match this; they are down by
approximately 20 to 30%, and now lilypond spends only 1/10th of the
running time in GC -- which seems reasonable to me. The numbers are
very sketchy, but that's because I keep forgetting to store my
benchmark results.
The bad news that now the need for Gen GC doesn't seem so pressing
anymore.
