Last month I upgraded my home server from 11.2-RELEASE to
12.0-RELEASE. It is ZFS only system. After making full data backup
with tar(1) I made clean install of 12.0-RELEASE and restored backuped
data. Then there is significant improvement of I/O performance.
Is it possible that I/O performance degrade while using ZFS for a long
time? And if answer is yes is there any way to recover performance
without making full backup and restore?
