I checked this by adding two (static) counters to `scm_gc_for_newcell ()': one that counts the number of calls, and one that counts the number of non-EOL returns of the first `scm_i_sweep_some_segments ()' call. The ratio (still for the same workload) is _always_ very, very close to 1. This is because `scm_i_sweep_some_segments ()' does not actually only sweep segments: it sometimes (actually here, most of the time) *initializes* them. The reason is that it uses `scm_i_sweep_some_cards ()' which in turn chooses whether to initialize or sweep depending on whether the segment at hand is already initialized (SWEEPER is chosen based on SEG->FIRST_TIME). This interleaving of initialization and sweeping makes it pretty hard to track exactly where fresh cells come from. I guess one solution might be to maintain a list of the uninitialized segments and pick cells directly from there before actually sweeping. To be continued... Hopefully! ;-) Thanks, Ludovic. _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://lists.gnu.org/mailman/listinfo/guile-devel
