>Those are interesting results. 
yes, indeed

>Does this mean you've already written lzo support into ZFS? 
no, i`m not a "real" coder, but there exists an lzo patch for zfs-fuse which 
has also been discussed here, afaik.
not sure if this has already been included in zfs-fuse tree - just wanted to 
check out, but website (http://www.wizy.org/wiki/ZFS_on_FUSE) seems down for 
the moment - if this takes longer to recover (happens often and normally 
doesn`t) maybe i have it left on my system somewhere where i tried zfs-fuse 
with lzo patch and where i did thos performance comparison.

>If not, that would be a great next step
if other performance comparisons give similar results, i really think so.
not sure, if my results are reliable, but at least it`s worth taking a closer 
look, because also eric dillman told, it would perform better than lzjb - at 
least with zfs-fuse.

>licensing issues can be sorted out later..
good attitude ! :)

zfs-fuse author/maintainer is Ricardo Correia and the lzo patch was done by 
Eric Dillmann. I can provide contact data if you like.
