comment Can (compiled) matrix permanent evaluation be further sped-up?
Using the matrix: m = N @ HilbertMatrix[20], your permanent is about 73 times faster than the built-in Permanent. Your cPermanent is about 493 times faster than the built-in. With option CompilationTarget -> "C" added to cPermanent we get about 775 times faster than built-in. Finally, changing "Quality" to "Speed" makes the function about 1765 times faster than built-in. These built-in functions are getting depressing. +1
