Hi Lidan,

With Goolge Chrome Frame, WebSockets on IE9 should work with Lightstreamer too. We will do further tests and let you know.

In any case, let me stress that for your usage scenario, WebSockets do not offer any better performance than HTTP Streaming. The real advantage of WebSockets arises for bi-directional communication, that is, when you send low latency updates FROM the client to the SERVER. Please see this slide and the previous slides in the same deck for a deeper explanation on the topic.

If you are still skeptical, then perform a test. Measure the bandwidth consumed by the same application when connected over WebSockets and over HTTP Streaming and compare them...

Thanks,
Alessandro
