My "not-so-meaningful benchmarks" (running a > loop[*]) reproductively show that "GBGC" is noticeably slower than "real > Guile" (1.5 to 2 times slower). tuning down GC_free_space_divisor to 2 sped things up a little bit, around 10 %. I'm now at 77sec (vs GUILE 1.8: 52 sec) I'm on dual-core nowadays, so real time it's actually still a bit faster, as BGC is multithreaded. -- Han-Wen Nienhuys - hanwen@xs4all.nl - http://www.xs4all.nl/~hanwen _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://lists.gnu.org/mailman/listinfo/guile-devel
