Maximum service time for I/O events (in microseconds).

C# |
public long ioEventsMaximumServiceTime()

Maximum service time for I/O events (in microseconds). This is the
high-water mark (i.e., the longest so far) for I/O event service durations
measured from the point of de-queuement until the application has finished
servicing the event. Configuration option queue_service_time_enabled must be
activated.
