# Asynchronous

Specifies whether to send requests asynchronously.

- When you send requests synchronously (`Asynchronous=false`), CFS sends one request to the translation service for each document, but the connection remains open until translation is complete and the results are returned. This option might be suitable when each request contains a relatively small amount of text.
- When you send requests asynchronously (`Asynchronous=true`), CFS sends multiple requests per document (because it polls the translation service to retrieve the results) but all of the requests are short-lived. Use this option if you expect to send large amounts of text from each document, because translation might take longer than is reasonable for a synchronous request.

The best value for this parameter depends on the performance of CFS and the translation service. Micro Focus recommends starting with the default value, and setting `Asynchronous=TRUE` if a large number of open connections begins to affect performance.
