Some data is not compressible (e.g. mpeg4 movies), so in that case you
won't see any improvements.

Thanks for your answer Fajar.

As I said in my initial mail, those zones are mainly only writing some Glassfish logs. Since they all are text files, I guess I can save a lot of space using compression. Hopefully I can even improve the performance. Can I?

However. What's the difference using

zfs set compression=on opt/zones/whatever_zone


zfs set compression=gzip-6 opt/zones/whatever_zone


zfs set compression=gzip-9 opt/zones/whatever_zone


I will face my fear. I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing. Only I will remain.
