You can configure asynchronous mounting on App Volumes Manager and agent to enable App Volumes Manager to handle a large number of login requests within a short time and improve scalability.
When you attach Writable Volumes or AppStacks, the App Volumes Manager has to keep a number of HTTP connections open until the volumes are all mounted. When asynchronous mounting is enabled, App Volumes Manager does not have to wait until all the volumes are mounted and can handle other requests concurrently.
When you perform a fresh installation of App Volumes, by default, asynchronous mounting is enabled on both the App Volumes Manager and agent .
If this setting is disabled for any reason, such as, when you upgrade App Volumes, you must change the settings on both the App Volumes Manager and the agent to enable it.
