Go strings manipulation: Optimize performance x100

Optimization, faster, better… these words are always what we search for on google to make our programs more performant. In a recent project I’ve worked on, the optimization was the main focus.

The tips below are the fruit of 2 months of work. These tips may not all fit your needs, test them all and choose what fits your code more.
