To sum up, BGC is always slower but usually more memory-efficient than GGC. In Guile + libgc, you could try adding: GC_set_free_space_divisor (2); right before `GC_expand_hp ()' in `libguile/gc.c'. AIUI, this would trade memory for CPU time. Ideally, we'd need a better benchmarking framework, where each benchmark is run tens of times and where both the average and variance are reported. Unfortunately, I don't have much time to work on it right now. Thanks, Ludovic. _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://lists.gnu.org/mailman/listinfo/guile-devel
