Chat application using django
I think for a chat application you can use other technologies, such as AMQP(RabbitMQ, etc), Comet, etc.
But, for develop user profile, PMs, and other you can use Django. 
Do not forget that performance still depends on server configuration (web server software, cache, db)
If i devlop a chat application using django will it have some performance problem?
Can i do server push in django?
I want to have PM and room discussions as well.
