Except this easy to easy to change from not compressed to compressed. Setting the attribute alone not work. If you think have to do send/recv everything to get it compressed is a pleasure task, especially you have to do this every time after you installed a new system, I have nothing to say anymore. Why don't it just the thing already set to be compressed from the beginning? It will save much time and space for the user!

BTW, FreeBSD seemed to turn on lz4 compression by default. Nowadays with modern hardware, it's sane to turn it on by default. Your arguments about an old system should be dismissed completely. None of the Illumos is for old and weak system. Illumos is a resource hog.
