VFS performance has been improved by better making use of multi-core machines. If you have ever used Local History to recover code you did not commit, the VFS is to thank for having stored your code in such cases. The VFS contains details about files, and also tracks changes made to files and folders. On startup, Rider builds a virtual file system (VFS) representation of your solution. Scanning and loading files and assemblies But even on solutions with fewer projects, such as Entity Framework Core, cold start should be noticeably faster. ![]() Orchard and Avalonia are both solutions with many projects, where our startup performance optimization really pays off. ![]() Here are some statistics from loading some open source projects: In the Rider 2022.3 release, we have improved this “cold start” time quite significantly. That’s a lot of work, but at the same time you probably want to start working on your code as soon as possible after starting your IDE. Rider then has to parse your solution and project file, run a design-time MSBuild, restore NuGet packages, enumerate all files in your solution, parse code and analyze the syntax, index symbols so code completion, navigation and refactoring becomes possible, and much, much more. There’s of course loading the IDE itself, with all of its built-in functionality such as Git tools, database tools, editors, and so on. When you start Rider and open a solution, a lot of work has to be done in order to make sense of your code. What happens during IDE startup and solution loading? ![]() Let’s have a look at some of the changes we made. Have you tried the latest Rider 2022.3 (Early Access Program) yet? It may feel faster than previous versions, because… it is! As part of the Rider 2022.3 release, we have been working on a number of performance improvements to make solutions load faster, speed up syntax highlighting when opening editor tabs, and more.
