Not sure what "compression=gzip" will give you. I believe you might be
safer using "compression=gzip-6" or whichever value you want to use.
gzip9 will be pretty slow if that's the default for "gzip".

I use lzjb because there isn't much advantage to gzip, at least in my
experience, and lzjb is fast. I did some testing and didn't find a big
space savings with gzip-6 or gzip-9.


% zfs get compressratio
