In the world of C++, performance is key, which often leads programmers to explore various optimization techniques, including the use of the “final” keyword. While many claims suggest that using “final” can enhance performance, a detailed examination shows mixed results, with performance improvements seen in some scenarios and performance hits in others. Extensive testing across multiple machines, operating systems, and compilers reveals that final’s impact varies significantly depending on the specific configuration and scene. Ultimately, the decision to use final should be based on thorough testing and measurement tailored to your individual setup, with Clang and MSVC potentially not being the best fit. The project offers a detailed exploration of these findings and provides valuable insights for C++ developers aiming to boost performance.
