:::moniker range=">= aspnetcore-8.0"

Without enabling AOT compilation, Blazor WebAssembly apps run on the browser using a .NET [Intermediate Language (IL)](/dotnet/standard/glossary#il) interpreter implemented in WebAssembly with partial [just-in-time (JIT)](/dotnet/standard/glossary#jit) runtime support. Because the .NET IL code is interpreted, apps typically run slower than they would on a server-side .NET JIT runtime without any IL interpretation. AOT compilation addresses this performance issue by compiling an app's .NET code directly into WebAssembly for native WebAssembly execution by the browser. The AOT performance improvement can yield dramatic improvements for apps that execute CPU-intensive tasks. The drawback to using AOT compilation is that AOT-compiled apps are generally larger than their IL-interpreted counterparts, so they usually take longer to download to the client when first requested.
