Internet Speed Test автор Ray

This extension can be used to measure real-time and average internet connection speed either to the nearest center or a center that is specified by user.

The extension provides a toolbar panel for easy internet measurements. In the settings page you can find a server that is located in a particular region of interest (by default the fastest server gets selected for measurement).
