I'm trying to read from disk opening maildir with 20000 mails with mutt. If I open that maildir, mutt shows progress. With cfq or anticipatory scheduler, progress is 0/20000 until scp finishes. With deadline, progress is 150/20000 after scp finished. So I would say, it is better but I doubt it is OK. -- Lukáš Hejtmánek -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
