Röck Yoür Cöde: Stop Guessing—Benchmark Like a Pro

Advanced English

You think your code is fast? Prove it. Modern .NET developers have more tools than ever—but too many are still guessing when it comes to performance. The result? Slower applications, higher cloud costs, and problems that don’t show up until production. And here’s the kicker: even AI tools like GitHub Copilot can generate code that compiles, works… and performs terribly. If you’re not measuring it, you’re trusting it—and that’s a risk. In this session, veteran engineer and author David McCarter (dotNetDave) shows how to cut through the noise and make performance a data-driven discipline. Using BenchmarkDotNet and the DotNetTips.Spargine.Benchmarking library, you’ll learn how to measure execution time, memory allocation, and scalability the right way. Through live demos and real-world examples, you’ll see just how wrong “common knowledge” about .NET performance can be. You’ll learn how to build benchmarks you can trust, avoid traps like JIT optimizations and setup bias, and turn raw numbers into decisions t
