Performance Profiling

Definition

Performance profiling is the process of measuring and analyzing the efficiency of a system or application, particularly to identify bottlenecks and areas for improvement. This technique is crucial for optimizing the performance of microcontrollers in robotics, ensuring that tasks are executed efficiently and resources are used effectively. Additionally, performance profiling aids in testing and troubleshooting robotic systems by providing insights into how well the components work together under various conditions.
