Difference with other similar systems
First of all, this service is different from the other very small update period (default value is 8 seconds). In other systems, this period is usually 60-90 seconds. In addition, through a unique "engine", updates are applied only for those vessels, the dynamic data that actually changed. Also, if possible, optimization and compression of the data occurs. In other systems, as a rule, all ships updated on the map. For example, for ~ 200 visible vessels and compression of data: the initial loading of data 9-10 kb, data updates (for the 8-second period), 2-4 kb, depending on traffic intensity.
