Those should still work. What prevents them from being effective markers today is that no matter how much memory you have, a write heavy workload (one that dirties data faster than disk drain) will consume whatever you have and trigger the markers. If you don't have the above problem, then anonymous paging is a good sign of memory shortage. -r > Thanks in advance, > Dmeetry > > > This message posted from opensolaris.org > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
