ESP-IDF ships with default settings that are designed for a trade-off between performance, resource usage, and available functionality.
These guides describe how to optimize a firmware application for a particular aspect of performance. Usually this involves some trade-off in terms of limiting available functions, or swapping one aspect of performance (such as execution speed) for another (such as RAM usage).
How to Optimize Performance
Decide the performance-critical aspects of your application, such as achieving a particular response time for a certain network operation, meeting a particular startup time limit, or maintaining a certain level of peripheral data throughput.
Find a way to measure this performance (some methods are outlined in the guides below).
Modify the code and project configuration and compare the new measurement to the old measurement.
Repeat step 3 until the performance meets the requirements set out in step 1.
- Speed Optimization
- Minimizing Binary Size
- Minimizing RAM Usage
