When updating from a 2010.Q3 release to a 2011.1 release, the following deferred updates are available and may be reviewed in the Maintenance System BUI screen. See the "Maintenance:System:Updates#Deferred_Updates" section in the online help for important information on deferred updates before applying them.

1. RAIDZ/Mirror Deferred Update (Improved RAID performance)
*1. RAIDZ/Mirror Deferred Update (Improved RAID performance)*
This deferred update improves both latency and throughput on several important workloads. These improvements rely on a ZFS pool upgrade provided by this update. Applying this update is equivalent to upgrading the on-disk ZFS pool to version 29.

*2. Optional Child Directory Deferred Update (Improved snapshot performance)*
This deferred update improves list retrieval performance and replication deletion performance by improving dataset rename speed. These improvements rely on a ZFS pool upgrade provided by this update. Before this update has been applied, the system will be able to retrieve lists and delete replications, but will do so using the old, much slower, recursive rename code. Applying this update is equivalent to upgrading the on-disk ZFS pool to version 31.
