For example, you could add a custom header `X-Process-Time` containing the time in seconds that it took to process the request and generate a response:

/// tip

Here we use <a href="https://docs.python.org/3/library/time.html#time.perf_counter" class="external-link" target="_blank">`time.perf_counter()`</a> instead of `time.time()` because it can be more precise for these use cases. 🤓
