Andriy Gapon 457711b02b MFV r316922: 5380 receive of a send -p stream doesn't need to try renaming snapshots ... illumos/illumos-gate@471a88e499 471a88e499 https://www.illumos.org/issues/5380 A stream created with zfs send -p -I contains properties of all snapshots of a given dataset as opposed to only properties of snapshots in a given range. Not only this is suboptimal but the receive code also does not filter properties by the range. So, properties of earlier snapshots would be updated even though the snapshots themselves are not in the stream (just their properties). Given that modifying the snapshot properties requires a TXG sync and that the snapshots are updated one by one the described behavior may lead to a sever performance penalty.
