Also up the number of iterations the swift benchmark in the stdlib runs so that it matches the number of iterations the c++ version does. This iteration number is enough to cause the c++ version to run for ~1 second. With this same number of iterations, the swift version takes ~10 seconds. Swift SVN r15205
