hi,

compression on zfs has basically zero disadvantage, it's also set by default unless you unset it.
you can check the current value with zfs get compression POOLNAME (or simply without POOLNAME will give you all)

if you're looking to tune performance with ZFS you can look here [0] and also our wiki page [1] [2]

My question was about whether it is convenient to activate it in the PBS, which it already compresses, or is it not convenient for performance reasons
Thanks
