Using -pipe is a big win. On a system with not enough RAM, and not using
-pip, the stuff gets written to intermidiate files. If this is an MFS /tmp
then this is swap, else it is ordinary file system. On a system with less
memory and -pipe the processes get swapped. If the swapper/pager is good
enough then what is the difference ?
On a system with lots of mem -pipe is a major winner. My default editing
procedure for config generated Makefiles.
