The credit is reset to zero after each sent. > * That way, messages are sent as often as the network has capacity and > contain as much credit as available for the channel at that point in time. > Otherwise, it would only add latency to the announcements and not increase > throughput. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
