Lines of Code and Optimisation

Hi, I'm relatively new to programming and I have a question.

Does few LoC == faster? Or is it in the algorithm itself? Is there an instance where more LoC is faster than the shorter one?

Cudder, silly fucktard, go write PHP code, because you shouldn't use broken memcpy: http://lwn.net/Articles/414467/

moreover, compilers have "optimize for size" option, so GCC should provide correct version of malloc for correct CPU, you chosen.
