2x-3x Performance Improvements for Debug Builds

May 7, 2021 May 7, 2021 05/7/21

Pranav Kant

We have made substantial runtime performance improvements in the x86/x64 C++ compiler for Visual Studio's default debug configuration. For Visual Studio 2019 version 16.10 Preview 2, we measure 2x - 3x speedup for programs compiled in debug mode. These improvements come from reducing the overhead introduced by runtime checks (/...

Russell Hadley

On the C++ team we’ve heard loud and clear from users that build times are a pain point. We’ve continued our focus on improving the step, linking, that dominates F5 build times. Fast F5 build times, or iteration build times, are a key contributor to developer productivity and we felt that there was a large opportunity so we narrowed in on ...

YongKang Zhu

In Visual Studio 2019 Preview 2 we made the compiler back-end to prune away debug information that is unrelated to code or data emitted into binary and changed certain hash implementations in the PDB engine, to improve linker throughput, which resulted in more than 2x reduction on link time for some large AAA game title. Debug Info Pruning...

Visual Studio 2017 Throughput Improvements and Advice

January 4, 2018 Jan 4, 2018 01/4/18

Terry Mahaffey

点这里看中文版 As C++ programs get larger and larger and the optimizer becomes more complex the compiler's build time, or throughput, increasingly comes into focus. It's something that needs to be continually addressed as new patterns emerge and take hold (such as "unity" builds in gaming). It's something we're focusing on here in the...

Continuing with our goal of further improving developer productivity with Visual Studio 2017 there have been major investments made for also improving incremental developer builds. The developer incremental build is one where a developer changes a single or multiple source files and builds. The time spent in these builds is almost equal to the...
