Published Benchmarks and DDOS

[Dor Tzur]

First of all, I would like to mention that i really like this
framework and i think you guys are doing an amazing job. I got into
Node just recently after reading an article about your framework.
I have 2 questions.

A. Are their any published benchmarks of now that i can use to show
the guys upstairs?

B. I'm new to Node and i would like to know 2 things:
1. What is the best way to make sure that only authenticated users can
send messages through now, should i prevent unauthenticated users from
accessing the now.js / socket.io client files or is there a better
way?
2. Can you please tell me how can i prevent DDOS attacks on the now
framework, or if there's a built-in mechanism in Node which i can use
that would also apply to now messages?

I'll answer the first.

Some work has been done benchmarking NowJS. NowJS has been tested to hit 10,000 concurrent connections, possibly more. 

NowJS for Enterprise edition (previously "NowCluster") has been benched to handle over 500,000 concurrent connections and 500,000 messages per second. Theoretically, it should scale further but this hasn't been tested. It's still in private beta, and won't be released until we grow the Flotype team to handle the bandwidth.

I See, but there are no published results to date as i understand,
i'll pass it along thank you.

Any advice for DDOS attack prevention?
