Do you know why?

Here is a code:

I have try it with ldc too, but is still much slower (10x) than 
PHP

Looks like they added ldc to it. I'm seeing 3x slower than PHP on 
Email and URI, but roughly par on IP. It really stands out on the 
DMD one how much better it does on the IP one than the Email/URI 
ones.
