In this series I will detail what I found out empirically about how mochiweb performs with lots of open connections, and show how to build a comet application using mochiweb, where each mochiweb connection is registered with a router which dispatches messages to various users.

with details how to tweak the kernel and make a flood test

A Twisted-based publish/subscribe messaging server that uses the STOMP protocol

Comet doesn’t have to be a hack. Currently, as we saw last time, Comet relies on undocumented loopholes and workarounds, each one with some drawbacks. We can make Comet work effectively in every browser, using streaming transports on subdomains of the same second-level domain, or using script tag long polling across domains. But this leaves Comet developers implementing (and more frustratingly, debugging) several transports across several browsers. Traps are numerous and easy to stumble into.

event-source is the future of all Comet things.

Comet wrapper for the Mootools 1.2 JavaScript framework.

Cometd Bayeux is a publish/subscribe messaging system, and this has drawn some criticism that PubSub is not the most flexible paradigm for an Ajax/Comet transport.

After some recent optimizations, the Dojo Cometd implementation of the Bayeux protocol running on the Jetty web server can now handle up to 20,000 simultaneous users per server while maintaining sub-second latency.

impressive numbers. Does the Twisted one can beat that?
