So what was that -j96 about?

 "-j96" is an option to GNU make, not to the compiler.  It might invoke
gcc multiple times in parallel, but each invocation of gcc will still be
single-threaded.
 

So, is there just once instance of gcc at work during those 13 minutes, or multiple?
In other words, would it take longer than 13:40 mins without it, or does it help? If -j96 makes no difference, then why specify it?
