My code seems to run much more quickly when I only use Parallelize[] as
compared to any combination of Parallelize and Compile.  Even when I compile
into C using CompilationTarget->"C" and with Parallelization->True.

I thought that compiling would always make a program in Mathematica run
faster. Why does it slow down?  Is Parallelize always the most efficient?
