Minimum service time for topic-less immediate messages (in microseconds).

C# |
public long topiclessImmediateMessagesMinimumServiceTime()

Minimum service time for topic-less Multicast Immediate Messaging (MIM)
messages (in microseconds). This is the low-water mark (i.e., the shortest so
far) for topic-less MIM message service durations, measured from the point of
de-queuement until the application has finished servicing the message.
Configuration option queue_service_time_enabled must be activated.
