There's also Locust, a Python powered load testing tool similar to this. It's focused on simulating user behavior rather than hitting specific URLs. This allows for much more true-to-life testing.
We used it to load test Battlelog (the online service for Battlefield 3) and successfully simulated over 2 million concurrent users hitting the service using EC2.
See http://locust.io for more info.
