While scrubbing is working on my 12 GB ZFS volume, updatin= g /usr/ports takes >25 min(!). That is an absolute record now. I do an almost daily update of world and ports tree and have periodic scru= bbing ZFS volumes every 35 days, as it is defined in /etc/defaults. Prts tree hasn't = grown much, the content of the ZFS volume hasn't changed much (~ 100 GB, its fill is ab= out 4 TB now) and this is now for ~ 2 years constant.=20 I've experienced before that while scrubbing the ZFS volume, some operation= s, even the update of /usr/ports which resides on that ZFS RAIDZ volume, takes a bit lo= nger than usual - but never that long like now! Another box is quite unusable while it is scrubbing and it has been usable = times before. The change is dramatic ...
