Profiling and Optimizing Go Applications

Writing functional Go code is only the first step; ensuring it runs efficiently under heavy production loads is what separates great software from the rest. This text-based course guides you through the essential techniques of Go performance analysis without the complexity. You will transition from guessing where performance bottlenecks lie to scientifically measuring and optimizing your code. Through step-by-step written explanations and practical code examples, you will learn to pinpoint CPU spikes, memory leaks, and inefficient allocations. What you'll learn: Understand the fundamentals of Go runtime behavior, garbage collection, and memory allocation; Write robust benchmarks using the standard library's testing package; Analyze CPU and memory profiles using the built-in pprof tool; Optimize memory usage by leveraging sync.Pool and understanding escape analysis; Configure modern runtime parameters like GOMEMLIMIT and GOGC for predictable performance; Interpret execution traces to diagnose concurrency issues and latency bottlenecks. The course begins with foundational concepts of Go's memory model and runtime execution, then moves systematically into practical benchmarking, profile generation, and real-world optimization strategies. You will read detailed explanations, analyze code snippets, and complete written exercises to reinforce your learning. This course is designed for Go developers who understand basic syntax and want to learn how to write faster, more memory-efficient applications. No prior experience with performance profiling is required. Start learning how to build high-performance Go applications today.
