Dan Elwell's Broadband Speed Test is a downloadable utility that can test your Broadband connection, identify any areas of concern, monitor performance over time and generate diagnostics you can use to send to your ISP. Project has been abandoned.
It's the ultimate connection monitoring and benchmarking tool and is great for those who want to diagnose connection problems or are simply curious about their performance.
This Speed Test is completely different from other Speed Tests available on the web. It's a downloadable utility for Windows, and that gives it a host of advantages over other Speed Tests. As well as being much more accurate and reliable than web-based Speed Tests, it has many more features, such as ping testing, traceroutes, result archiving and file exporting/printing. It's a fully featured connection benchmarking tool.
