CPU profiling
CPU profiling is the process of analyzing how much CPU time is consumed by different sections of your Go program. This analysis helps you identify the following aspects:
- Bottlenecks: Code areas using excessive CPU time, slowing down your application
- Inefficiencies: Functions or code blocks that can be optimized to use less CPU resources
- Hotspots: The most frequently executed parts of your program, the prime focus for optimization
To exercise profiling, we’ll create a file change monitor. The program will monitor a specified directory for file changes. To make the scope concise, our program will detect file creation, deletion, and modification. Also, upon detecting changes, it sends alerts (printed to the console).
The complete code can be found in this book’s GitHub repository. For now, we are exploring the core features and the corresponding code sections so that we have a clearer understanding of how it operates:
