Faster builds with PCH suggestions from C++ Build Insights
The creation of a precompiled header (PCH) is a proven strategy for improving build times. A PCH eliminates the need to repeatedly parse a frequently included header by processing it only once at the beginning of a build. The selection of headers to precompile has traditionally been viewed as a guessing game, but not anymore! In this article, we will show you how to use the vcperf analysis tool and the C++ Build Insights SDK to pinpoint the headers you should precompile for your project. We’ll walk you through building a PCH for the open source Irrlicht project, yielding a 40% build time improvement.
