It's not *extra* diskspace (if I read your intention correctly).   
swapfile.front is just a view onto swapfile; the only file that occupies  
real disk space is swapfile.

Apart from that, I'd would also like to know what good turning it on will  
do.  I find it hard to be convinced that compressing (which takes time) a  
swapfile (which MUST be fast) is a good idea.
