Adding unsafe can even slowdown your code. The unsafe block prevents the compiler from making certain assumptions, which can prevent some optimizations from happening. 'unsafe' is like telling the compiler 'trust me on this', and the compiler (not fully understanding what is going on in there) wisely decides not mess with what you wrote.
