 ## Improved support for devices with extreme memory constraints
 
-Although the Web Workers use only a minimal amount of memory, you can reduce the memory usage by running only one of the Web Workers at a time. This is recommended only if you have severe memory constraints that you can not address any other way. Normally when both **AcauntImageWorker** and **AcuantMetricsWorker** are running simultaneously, they seamlessly make calls between themselves until they are ready to return a finished image that has been cropped and has had all the metrics run on it. If only one is running at a time, the workflow has to look like this:
-
-- AcuantImageWorker is started to perform detect in your custom camera implementation
-- AcuantImageWorker is ended and AcuantMetricsWorker is started to perform moire on the uncropped image
-- AcuantMetricsWorker is ended and AcuantImageWorker is started to crop the image
-- AcuantImageWorker is ended and AcuantMetricsWorker is started to perform the remaining metrics on the cropped image
-
-Starting and stopping Workers is a very slow operation, so you will see performance losses with this approach. Therefore, use this approach only if absolutely necessary. See [Reference of AcuantJavascriptWebSdk methods](#reference-of-acuantjavascriptwebsdk-methods) for more information about the methods.
+See the single worker model in [Initialize and Start the SDK](#initialize-and-start-the-sdk).
