.NET 11 performance work is landing across the stack 🔥

Microsoft published the running list of performance improvements headed for .NET 11. This is not one magic runtime switch. The work spans the runtime, JIT, libraries, and tooling paths that show up in normal application code.

Use the post as a migration checklist:

• Find code that is CPU-bound, allocation-heavy, or called per request.
• Run your benchmarks on the .NET 11 SDK, not a synthetic microbenchmark only.
• Check p50 and p99 latency, allocations, startup, and throughput separately.

The best upgrade wins are boring: existing C# gets faster with fewer code changes. But measure your service. A JIT win can disappear behind JSON, EF queries, network calls, or a container CPU limit.
