: Facebook real time updates - How soon? Facebook sends real time updates to the app when one of the app's users changes the fields the app is subscribed to. https://developers.facebook.com/docs/graph-api/real-time-updates/v2.2

Facebook does not delay notifications rather it queues them. All real time updates are added to a queue to be processed and sent in turn by the servers Facebook uses to send real time updates to apps. The queue is there to ensure all updates are sent. Depending on the load Facebook is under at the time it could be anywhere from a few seconds to several minutes but given the size of Facebook and their global infrastructure it is unlikely that delays would get much more than a few minutes as they would have the ability to spin up new servers to help process the queue.
