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).
- Decide what the performance-critical aspects of your application are (for example: a particular response time to a certain network operation, a particular startup time limit, particular peripheral data throughput, etc.).
- 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.
Execution Speed <speed> Binary Size <size> RAM Usage <ram-usage>
