Performance Improvements in .NET 9

Each year, summer arrives to find me daunted and excited to write about the performance improvements in the upcoming release of .NET. “Daunted,” because these posts, covering .NET 8, .NET 7, .NET 6, .NET 5, .NET Core 3.0, .NET Core 2.1, and .NET Core 2.0, have garnered a bit of a reputation I want to ensure the next iteration lives up to. And “excited,” because there’s such an abundance of material to cover due to just how much goodness has been packed into the next .NET release, I struggle to get it all written down as quickly as my thoughts whirl.

In EF7, SaveChanges performance has been significantly improved, with a special focus on removing unneeded network roundtrips to your database. In some scenarios, we’re seeing a 74% reduction in time taken – that’s a four-fold improvement!
