The ORTC network is Realtime's secret sauce, providing low-latency message transfers simultaneously to millions of clients. (At the time of this writing it is handling 706,506 messages per second and has serviced 165,668,475 connections in the last 24 hours.)
Realtime also has great demos and tutorials."
