In our line of work we end up making some pretty neat tools. Check out all of our open source projects here.
Hammerhead
Hammerhead Details
Firebug Add-on for measuring the load time of web pages. Hammerhead makes it easier to gather performance metrics early in the development process, resulting in a faster development cycle. The biggest bias is that most developers have a much faster bandwidth connection than the typical user. Easy-to-install bandwidth throttlers are a solution. Steve Lamm blogged on Google Code about how Hammerhead can be used with bandwidth throttlers on the dev box, bringing together both ease and greater precision of performance measurements.
