Bandwidth Comparison
Latency comparison 
This shows significant difference for both bandwidth consumption & latency which shows that the Lightstreamer scales better than simple socket IO.
The Lightstreamer engine implements publisher subscriber model. Lightstreamer uses the long-polling technique
It basically has three components 
1. Server side implementation-coded in java(Lightstreamer server)
3. Adapters to support diversity of data exchange platforms
The server consists of java process. This process controls the Network messaging stack & threads which helps the process to achieve maximum optimization for the returning the data.
The servers use java NIO framework to scale up with huge number of connections
It uses advanced techniques which allow data transfer without being blocked by the firewall
The server continuously pushes the data to client (streaming) which is then displayed in UI by client
As shown in the below diagram we have
Two sets of adapters in the architecture
While creating a new lightstreamer session, the client can select the adapter to use. Each lightstreamer session needs the adapter set which includes one metadata adapter & multiple data adapters. These adapters are customized components which reside on server. These adap...

... Lightstreamer framework is useful for real time data updates for applications like chat rooms, blogs, notifications, Web site live data updates etc.
• Monitoring and telemetry:NASA Is Using Lightstreamer to dispatch the real time data coming from the satellites
• Telecommunication & media: Lightstreamer is the best solution for providing live feeds for sporting events
• Transport system monitoring & updates
• Web Mail system
• Public utility services
Lightstreamer provides a framework for push technology implementation in which real time data updates & exchange is achieved with low delays & high scalability. It’s an emerging form of Message oriented middleware which allows applications to send real time messages over internet & is firewall friendly which is gaining popularity in industry especially in domains which require real time web experience.
