MySpeed Server for Mac

From Visualware:

MySpeed provides accurate Internet speed testing for visitors to your website, enabling end users to test their bandwidth performance for both upload and download data transfers. Speed test results are provided in an easy-to-read comparison chart showing the spectrum from slow dial-up connections to high-end T4 lines. In addition to connection speeds, MySpeed measures Quality of Service, roundtrip time and maximum pause. As a Java applet, MySpeed can be easily hosted on any platform running a standard Web application server. The Professional option logs test results in a repository for web-based access, useful for help desk environments and managing bandwidth-hungry applications such as VoIP and multimedia.
