(In reply to Laurent Frigault from comment #4)
After running a few mariadb sql import jobs  I found that increasing
vfs.zfs.vdev.trim_max_active from 2 to 2000 under freebsd13 only decrease the
time of the job by 1 minute for  1h30 import (about 1 % gain).

=> No big gain with trim_max_active increase  on freebsd13
