Software Performance Fundamentals: Avoiding Common Pitfalls

Writing code that works is only the first step; writing code that runs efficiently under load is what separates junior developers from professionals. Many software projects suffer from slow response times and high resource consumption due to avoidable architectural and coding mistakes. This text-only course guides you through the foundational concepts of software performance, helping you spot common anti-patterns before they reach production. You will learn how to analyze code efficiency, understand memory usage, and apply optimization strategies to keep your applications running smoothly. What you'll learn: Understand core performance metrics like latency, throughput, and resource utilization; Identify common performance pitfalls such as N+1 query problems, memory leaks, and blocking operations; Apply basic profiling and benchmarking techniques to locate bottlenecks in your code; Implement modern asynchronous programming patterns to improve application responsiveness; Optimize data structures and algorithmic choices for better memory and CPU efficiency; Practice writing clean, maintainable code that scales gracefully under user load. The course begins with essential performance terminology and measurement concepts before moving into practical code optimization patterns, memory management, and modern concurrency strategies. Designed for beginner software developers and computer science students who want to write more efficient code, this course requires no prior performance engineering experience.
