Fog A. Optimizing software in C++. An optimization guide for Windows, Linux, and Mac platforms

Lyngby: Technical University of Denmark, 2019. — 175 p.This manual is for advanced programmers and software developers who want to make their software faster. It is assumed that the reader has a good knowledge of the C++ programming language and a basic understanding of how compilers work. This manual is based mainly on my study of how compilers and microprocessors work. The recommendations are based on the x86 family of microprocessors from Intel, AMD and VIA including the 64-bit versions. The x86 processors are used in the most common platforms with Windows, Linux, BSD, and Mac OS X operating systems, though these operating systems can also be used with other microprocessors. Many of the advices may apply to other platforms and other compiled programming languages as well.Choosing the optimal platform.
