title: How to create a simple cpu benchmark?
body: <p>For a school project, which is highly relevant for our A-Levels, we want to overclock a Raspberry Pi's CPU and evaluate the performance of the CPU, prior to and post overclocking it, with a self-written benchmark.</p>
  
  <p>This benchmark should be as simple as possible as it only repesents a smaller part of our presentation.</p>
  
  <p>We thought it might be a good idea to use <b>c++</b> as the language since it uses less resources(?).
  For the benchmark itself we thought about using somthing like an algorithm that calculates Pi or prime numbers to a specific point and see how long it takes.</p>
  
  <p>How can we use multiple cores/a single core?</p>
  
  <p>Are there a better/simpler alternatives to our thoughts?</p>
  
  <p>Thanks in advance.</p>
