Using Nodejs and Socket io

Question

I want to make an 'online chat module' for a supporting website. the project must be done by nodejs. so I want to use socket io library for this purpose. how many current users could the socket.io support? what type of os and hardware do you recommend? thank you.

Answer 1

It depends upon your server OS, configuration, hardware, network and traffic profile, but there are socket.io configurations that support tens of thousands of connections so 100 should be easy.

See these for more info:
