Show HN: Less Slow C++

Learning to Write Less Slow C, C++, and Assembly Code The benchmarks in this repository don't aim to cover every topic entirely, but they help form a mindset and intuition for performance-oriented software design. It also provides an example of using some non-STL but de facto standard libraries in C++, importing them via CMake, and compiling from source. For higher-level abstractions and languages, check out less_slow.rs and less_slow.py . Much modern code suffers from common pitfalls, such as bugs, security vulnerabilities, and performance bottlenecks. University curricula often teach outdated concepts, while bootcamps oversimplify crucial software development principles. This repository offers practical examples of writing efficient C and C++ code. It leverages C++20 features and is designed primarily for GCC and Clang compilers on Linux, though it may work on other platforms. The topics range from basic micro-kernels executing in a few nanoseconds to more complex constructs invol ... Read full article.
