The correlator sends events to multiple receivers. Sometimes, a receiver cannot consume its events fast enough for the correlator to continue sending them. When this happens, the default behavior is that the correlator suspends processing until the receiver disconnects or starts consuming events fast enough. In other words, a slow receiver can prevent other consumers from receiving events. However, you might prefer to have the correlator disconnect a slow receiver and continue processing and sending events to other consumers. Information in this section can help you determine whether to disconnect slow receivers.
