Can't really say.

When the code first appeared in stable I moved two of my machines 
(desktops) to LZ4 recreating each dataset. To my surprise gain at 
transition from lzjb was fairly minimal and sometimes LZ4 even loses to 
lzjb in compression size. However better compression/decompression speed 
and moreover earlier takeoff when data is incompressible clearly makes 
lz4 a winner.
