| | [AI summary] The article discusses the limitations of compilers in optimizing code and highlights the importance of understanding memory and CPU performance. It argues that modern programming languages are not optimized for current hardware, leading to inefficiencies. The author demonstrates that data-oriented programming can significantly improve performance by reducing memory access and leveraging CPU cache. However, object-oriented approaches are still popular due to their simplicity and historical influence, despite their performance drawbacks. The article also touches on other factors like memory bandwidth, disk I/O, and the importance of data layout for performance.
