Continuous trim (on zfs and ufs) comes sometimes with a large, and
unpredictable performance impact (same on linux with xfs[1]).
However trim on freebsd is extremely slow compared to..well everything else
(1.5 h for my 250GB SSD)
A cronjob (outside busy-hours) with something like "fstrim -v /" worked better
for me.
