![]() ![]() Follow the steps from the Case study: using vcperf and WPA to create a PCH for the Irrlicht 3D engine section to collect a trace of the Irrlicht solution rebuild.MSVC’s installation directory is typically: C:\Program Files (x86)\Microsoft Visual Studio\2019\ /TopHeaders folder, starting from the root of the repository.This file is the C Build Insights WPA add-in, which must be available to WPA for correctly displaying the C Build Insights events. Copy the perf_msvcbuildinsights.dll file from your Visual Studio 2019’s MSVC installation directory to your newly installed WPA directory.Obtain WPA by downloading and installing the latest Windows ADK.Download and install the latest Visual Studio 2019.Follow these steps to obtain and configure vcperf and WPA: ![]() The latest version is available in Visual Studio 2019.ġ. The examples in this article make use of vcperf, a tool that allows you to capture a trace of your build and to view it in the Windows Performance Analyzer (WPA). We’ll walk you through building a PCH for the open source Irrlicht project, yielding a 40% build time improvement. 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. A PCH eliminates the need to repeatedly parse a frequently included header by processing it only once at the beginning of a build. ![]() The creation of a precompiled header (PCH) is a proven strategy for improving build times.
