C# is working hard to be Rust-like in certain areas of performance. Part of Visual Studio's problem is that they can't yet take advantage of it in some key areas because they are still dependent on the Legacy Framework and Legacy WPF and have to migrate to modern .NET.
Cold boot perf is a good yard stick but it’s not that important in your workflow. Except when it crashes. They really should work on that. Quality as a feature.
