Thanks for doing this!
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.
