Few things that cause the slightly lower performance in native AOT apps right now. First (in apps using the web SDK) is the new DATAS Server GC mode. This new GC mode uses far less memory than traditional ServerGC by dynamically adapting memory use based on the app's demands, but in this 1st generation it impacts the performance slightly. The goal is to remove the performance impact and enable DATAS for all Server GC apps in the future. Second is CoreCLR in .NET 8 has Dynamic PGO enabled by default, which allows the JIT to recompile hot methods with more aggressive optimizations based on what it observes while the app is running. Native AOT has static PGO with a default profile applied and by definition can never have Dynamic PGO. Thirdly, JIT can detect hardware capabilities (e.g. CPU intrinsics) at runtime and target those in the code it generates. Native AOT however defaults to a highly compatible target instruction set which won't have those optimizations but you can specify them at compile time based on the hardware you know you're going to run on. Running the tests in video with DATAS disabled and native AOT configured for the target CPU could improve the results slightly.
