Performance Analysis and Optimization of C++ Standard Libraries
Explore performance analysis and optimization techniques for C++ standard libraries in this CppNow conference talk. Dive into improvements made to libcxx and libstdc++, including enhancements to algorithms like string::find and basic_streambuf::xsgetn. Learn about the development of std-benchmark for cross-library performance analysis. Examine ongoing performance issues and potential solutions, such as optimizing number parsing in stringstream and improving std::sort. Gain insights into effective use of C++ standard libraries, including best practices for containers like std::vector and std::string. Discover the impact of compiler optimizations and function attributes on library performance. Benefit from lessons learned through extensive analysis of C++ standard libraries, covering topics like algorithm selection, container usage, and language features.
