Perl versus PHP fastest programs

Always look at the source code. These are only the fastest programs.

If they are manually vectorized SIMD, does the host language matter? You might not be interested in the most optimised programs.

Look at "mandelbrot" or "spectral-norm" or other measurement tables. Look at the other programs. Choose which programs you want to compare.
