The book includes guidance on diagnosing GC-related issues using free profilers, analyzing heap memory problems, and understanding new GC configuration options introduced in recent .NET versions.

What's new in the 2nd edition of Writing High-Performance .NET Code?

The 2nd edition of Writing High-Performance .NET Code features a 50% increase in content with new examples, code samples, and diagrams throughout. It covers modern .NET features including ref-returns, value tuples, SIMD support, and Spans, along with expanded Visual Studio usage and more benchmarking techniques. The updated edition addresses .NET Core improvements, code warmup strategies, more detailed LINQ analysis, and tips for high-level frameworks like ASP.NET, ADO.NET, and WPF.

What tools does Writing High-Performance .NET Code recommend for profiling?

Writing High-Performance .NET Code recommends multiple free profiling tools to quickly identify performance bottlenecks in .NET applications. Ben Watson provides tutorials for using Visual Studio's profiling features, performance counters, and ETW (Event Tracing for Windows) for instrumentation. The 2nd edition significantly expands tool coverage, teaching developers how to analyze heap memory, diagnose JIT warmup problems, and use various profilers to measure both application and .NET framework performance.

Beyond the Speed Limits: Unleashing .NET's True Potential

00:00

Imagine joining Microsoft's Bing team with a seemingly impossible task: build one of the world's fastest server applications using .NET-a framework many dismiss as "too slow for serious work." This was Ben Watson's reality in 2008, and the result? A system handling millions of low-latency requests across thousands of machines. The conventional wisdom that managed code can't compete with native code for performance isn't just outdated-it's fundamentally wrong. The truth is .NET makes it easy to write slow code when developers are careless, but with the right knowledge, it can deliver exceptional performance. Most bottlenecks stem from poor coding patterns rather than the framework itself. The modern JIT compiler employs sophisticated optimizations that can sometimes outperform native code, especially in memory allocation speed and fragmentation handling. "Measure, measure, measure!" This isn't just advice-it's the cardinal rule of high-performance .NET development. Even seasoned developers can be dangerously misled by intuition. Remember when Watson's team incorrectly blamed memory usage on a large dataset, only to discover it was actually assembly loading overhead? Before collecting performance data, define precisely what you're measuring-"memory" could mean private working set, commit size, heap size, or dozens of other metrics. Goals must be quantifiable: not "make it fast" but "working set memory usage should never exceed 1GB during peak load of 100 queries per second."
