I used the gc benchmark program posted by Han-Wen:
http://www.mail-archive.com/guile-devel@gnu.org/msg01077.html
libgc (v6.8) was compiled with the --enable-threads=posix only.
For normal guile I used 1.8.1, default gentoo build. (-O2)
For GC guile, I built from your tree. (also -O2)
Snd is snd-ls V0.9.7.12.
My machine is an XP2800, single processor.
Running the benchmark program directly in guile gives no difference. Both
spent about 50 seconds running the test.
Inside snd is another matter:
[1] [2] [3]
Guile gc 96mb 176mb 54s.
Boehm gc 99mb 107mb 118s.
[1] Memory before running test reported by top.
[2] Memory after running test reported by top
[3] Time to run test in seconds.
All tests performed twice to ensure nothing special happened in one of
them. The numbers here are from last test, and are about the same as
from the run.
