It's just a matter of time.

Especially it's open source and aimed to be the leading framework of ajax.

I've done another implementation and a simple benchmark comparison (compare with ZK Comet),

Conclution

WebSocket do double (or more) work with 1/4 ~ 1/3 CPU Usage and double Memory Consumption (compare with ZK Comet).

Sorry to get in in such an old post... Are there any news about this? I was also thinking that WebSockets could bring huge performance improvements, especially on high latency networks. My first analysis on performance showed that I have many small (few hundred bytes) packet traffic between server and client, but each takes over 170 msec if my server is overseas. This leads to poor performance. Websocket should help with this, as the overhead of establishing an http connection for each request could be avoided.

Thanks
