However, we don't know what proportion of the time is spent between marking and sweeping. This makes it difficult to tune the GC as we're not sure where to focus our efforts on. This PR adds keys `marking_time` and `sweeping_time` to GC.stat for the time spent marking and sweeping, in milliseconds. -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
