Performance Improvements in .NET 11 documents a year of JIT and library work against the 11.0.0 release candidate

Sources: primary, discussion
Summary: The post covers a year of work in the JIT and the core libraries, including deabstraction, guarded devirtualization and wider escape analysis. Each claim ships with a self-contained BenchmarkDotNet case and the command to run it against both .NET 10 and .NET 11. The measurements are taken against 11.0.0-rc.1 rather than a final release.
Why it matters: The changes sit in the runtime and the libraries, so applications pick them up on upgrade without source changes.
