Showing results for performance - C++ Team Blog

The 1.25 release of the C++ extension in Visual Studio Code introduces a new way to understand your code faster with GitHub Copilot-powered symbol summaries, as well as new customization options for recursive #include path processing. With these enhancements, you gain AI-powered insights into unfamiliar or undocumented code and can optimize Intelli...

In the latest releases of the C++ Extension in Visual Studio Code, we have focused on performance improvements and stability. A fast, responsive, and reliable development environment is essential for maintaining productivity, especially in large and complex C++ projects. These updates include many incremental optimizations that collectively speed u...

Overview Introduction In our previous two (part 1, part 2) blog posts we discussed how Office was thinking holistically about header units. In this installment we’d like to share the concrete steps taken to integrate header units into the build of Microsoft Word, and their effect on build throughput. Throughout the...

With our recent 1.19 release, performance was our biggest focus for the C++ Extension in Visual Studio Code. This included features like progressive population of IntelliSense results and faster symbol searching. With these enhancements, you can begin writing C++ code when opening a file quicker than ever before. Additionally, we also added support...

In Visual Studio 2022 version 17.6 we added a host of new ARM64 optimizations. In this 2nd edition of our blog, we will highlight some of the performance improvements to MSVC ARM64 compiler backend, we will discuss key optimizations in the Visual Studio 2022 version 17.7 for both scalar ISA and SIMD ISA (NEON). We started introducing these performa...

This blog post presents a selection of machine-independent optimizations that were added between Visual Studio versions 17.4 (released November 8, 2022) and 17.7 P3 (released July 11, 2023). Each optimization below shows assembly code for both X64 and ARM64 to show the machine-independent nature of the optimization. Optimizing Memory Across Block ...

In this blog we will explore one change the MSVC compiler has implemented in an effort to improve the codegen quality of applications in debug mode. We will highlight what the change does, and how it could be extended for the future. If debug performance is something you care about for your C++ projects, then Visual Studio 2022 version 17.5 is maki...

This blog post presents some of the optimizations the backend team has implemented for Visual Studio 2022.
