Over the years, plenty has been written about string performance, lots of comparisons between String.Concat and StringBuilder. Today I decided to do some of my own research into the subject and contribute to the knowledge already out there. More specifically, I'll be taking a look at the memory usage for various concatenation methods and compiler optimizations used to generate the IL.

The test scenario I defined consists out of several methods, each returning the same string. The string I created is supposed to resemble a real-life scenario. I identified five different ways of concatenating strings for my test. I will be taking a look at the numbers when calling each method once and inside a very small loop of 50 calls, which is another real-life number in my case.
