Profiling template metaprograms with C++ Build Insights


The use of templates in C++ programs can sometimes lead to longer builds. C++ Build Insights puts tools at your disposal for analyzing template usage patterns and their associated impact on build time. In this article, we show you how to use the vcperf analysis tool and the C++ Build Insights SDK to understand and fix problematic template patterns. We demonstrate the practical use of these tools through a case study in which we reduced build time for the Sprout open-source metaprogramming library by 25%. We hope these methods will help you approach your template endeavors with confidence!
