.NET 8 Performance Improvements

.NET 8 brings significant performance improvements across the board.

JIT Improvements

The JIT compiler has been optimized for better code generation:

// Before .NET 8
var result = SomeMethod();

// After .NET 8 - better inlining and optimization
var result = SomeMethod(); // Automatically inlined when possible

AOT Compilation

Ahead-of-Time compilation for smaller, faster applications:

dotnet publish -c Release -r win-x64 --self-contained true /p:PublishAot=true

Memory Improvements

• Reduced GC pauses
• Better memory allocation patterns
• Improved memory pressure handling

Conclusion

.NET 8 is the fastest .NET version yet. Whether you’re building web apps, APIs, or desktop applications, you’ll see performance gains.
