Benchmarking and Hotspot Optimization
Learn to benchmark code sections and apply targeted optimizations to critical performance paths.
What is Code Benchmarking?
Welcome to Benchmarking and Hotspot Optimization! In this lesson, we'll learn how to measure your code's performance and find areas for improvement.
Benchmarking is the process of measuring the performance characteristics of a program or a specific part of it. This usually involves running the code multiple times and collecting statistics like execution time and memory usage.
Why Benchmarking is Crucial
You might think you know which part of your code is slow, but often, intuition can be misleading. This is why the adage "Don't guess, measure!" is vital in performance tuning.
Benchmarking provides objective, empirical data to identify bottlenecks. Without it, you risk spending time optimizing the wrong parts of your application, leading to minimal or no performance gains.
