From the HN guidelines (http://ycombinator.com/newsguidelines.html):

If the original title begins with a number or number + gratuitous adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys." Exception: when the number is meaningful, e.g. "The 5 Platonic Solids."

Update: Thanks for respecting the HN guidelines and for improving the title.

I've been looking at SLAMD lately - http://www.slamd.com/. It's also distributed and can be controlled largely by a built in web interface. With many of the other distributed tools (JMeter, The Grinder) you have to muck around with the Java desktop app which is less than intuitive.

Chris Groskopf of the Chicago Tribune News Apps team just released Bees with Machine Guns (http://blog.apps.chicagotribune.com/2010/07/08/bees-with-mac...), which looks like a lot of fun.
