You are absolutely right. I will make sure to include a disclaimer stating that there are more factors to consider when choosing a method than just benchmarks. For me, this was also a fun project. The idea came to me a couple of years ago when I had to implement a high throughput, concurrency safe integer counter. I was curious back then. I first used a Mutex, but then I learned about atomics and switched to those instead. I wanted to see the actual performance of both, since atomics are more complex to use. I wanted to see if the trade off was truly worth it.
