Performance in the .NET Runtime
summary
Walks through concrete runtime work: shows how virtual stub dispatch rewrites call sites and reduced memory use and increased throughput, explains the JIT’s tiered compilation with a 30‑execution hot count and background recompiles, describes value‑type calling/boxing costs and method‑table pointer fixes, and cites a Kestrel micro‑optimization that adds about 40,000 requests/sec. Mentions tools and projects used or referenced like BenchmarkDotNet, RavenDB and the Raygun APM Platform and points to source and Book of the Runtime.
