Some questions I had after listening to Andrew Sliwinski discuss stress testing diy.org on the NodeUp podcast.

Hey Andrew! Thanks for offering to discuss your setup further. I fumbled around with stress testing late last year, but the method you described on NodeUp seemed so much simpler.

I haven't had a chance to use restify--is your logging as simple as a single handler that logs with node-bunyen, passed to server.use?

Does diy.org use WebSockets? Do you have a way to stress test that code? Does Load Impact support simulating WebSocket traffic?

I'm having a little trouble understanding Load Impact's pricing/credit structure. Could you give me an idea of the shape of the traffic you simulate, and what that translates into for credits?

Do you stress test your production system ([like Netflix](http://techblog.netflix.co
