Pawel Jakub Dawidek 1698a6aec9 Dramatically optimize listing snapshots when user requests only snapshot ... names and wants to sort them by name, ie. when executes: # zfs list -t snapshot -o name -s name Because only name is needed we don't have to read all snapshot properties. Below you can find how long does it take to list 34509 snapshots from a single disk pool before and after this change with cold and warm cache: before: # time zfs list -t snapshot -o name -s name > /dev/null cold cache: 525s warm cache: 218s after: # time zfs list -t snapshot -o name -s name > /dev/null cold cache: 1.7s warm cache: 1.1s MFC after: 1 week		2012-01-21 21:12:53 +00:00
