.NET 9.0 LINQ Performance Improvements
With .NET 9, LINQ becomes faster in several common scenarios. As with every new version of .NET, you simply need to migrate and recompile to take advantage of these improvements. Additionally, LINQ has been optimized in other ways: SIMD is utilized whenever possible, such as when summing a sequence of integers. Moreover, enumerating empty sequences incurs lower costs due to early detection.
