It&#x27;s a benchmark engineered to measure the performance of compilers and CPUs. It&#x27;s healthy to be skeptical but in general if you get a better score, it&#x27;s a real improvement. You should be able to safely exclude measurement errors and other mundane issues.<p>These benchmarks have a slight issue that they might not represent real world performance, but compilers and CPUs tend to be optimized against them - because their timing and measurement is generally more reliable than ad-hoc real world measurement. It might lead to slight &quot;over-optimization&quot; which doesn&#x27;t reflect real performance but at least it&#x27;s reliable and repeatable.
