However, this strategy does not fit practical + cases, for example too slow to make progres. + + This patch changes this strategy how many objects the + gc_marks_step() should handle. + + We can estimate how many times gc_marks_step() is called during + this major marking (== C) with the free slot number in pooled + pages. We also can estimate the living object number (== L) + using last marked_slots value. We can solve this problem (how + many objects should be process in gc_marks_step()) by L/C. + + * gc.c (rb_objspace_t): add rb_objspace_t::rincgc::pooled_sltos and + step_slots. + Fri Nov 14 01:26:47 2014 Shugo Maeda <shugo@ruby-lang.org> * lib/net/imap.rb (search_response): parse MODSEQ in SEARCH |
