By using non-blocking event-driven communication with a built-in thread-pooling mechanism, RealThinClient SDK can handle thousands of active connections by using a limited number of threads in a real multi-threaded environment (for example, 100 threads will be more than enough to handle several thousand active connections). Combined with reduced need for all important resources (CPU, Memory, Threads, Timers, Handles, etc), automatic handling of all communication-related objects, flexible remote functions (accept any structure for parameters and return any other structure as a result), automatic session handling (integrated time-out with variable life time) and a lot more, makes writing stable and fast Servers and Clients very easy with the RealThinClient SDK..in/images/2014/09/26/odSx.png[/img]
