# Async By employing this approach, tasks are dispatched for execution without necessitating immediate waiting for their completion. This mechanism enhances system efficiency and responsiveness. It does it because it enables the system to continue processing other tasks while awaiting the completion of the asynchronous task. This strategy aligns closely with the principles of sustainable design by optimizing resource utilization. Rather than idling or blocking resources, the system can allocate them to other tasks, minimizing wastage and conserving energy. This proves especially advantageous in scenarios where processing times might vary or when tasks don't require immediate feedback. **Asynchronous** calls not only enhance overall system performance. They also contribute to a more ecologically conscious software ecosystem, where resource efficiency is a cornerstone of sustainable systems design. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.umbraco.com/sustainability-best-practices/backend/async.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
