This example is very old. It does not work with the latest versions of Socket.IO.
A simple demo of a multiroom chat in Node.JS + Socket.IO with included simple benchmark.
Clone:
git clone git://github.com/jgonera/socket.io-multichat.git
cd socket.io-multichat
Install dependencies:
npm install
Run:
node app.js
or to disable logging and increase performance:
NODE_ENV=production node app.js
The app will be available at http://localhost:7890/. You can open a few tabs in your browser, join some channel and see how it works.
Start in production and then run:
node benchmark.js [TOTAL_CLIENTS] [CLIENTS_PER_ROOM]
This will connect TOTAL_CLIENTS clients to the server and start flooding
TOTAL_CLIENTS/CLIENTS_PER_ROOM rooms with messages. Setting this too high is
more likely to cause 100% CPU usage on the benchmark than on the app itself (so
run top to see if you reach the benchmark's limit or the app's limit).
