WiseLoop JavaScript Bandwidth Tester is a jQuery plugin that allows you to do a network speed test against your internet server. The script can check many server types (like Apache HTTP, Apache Tomcat, IIS, nginx, Oracle HTTP, jetty etc.) as long as the server supports POST and GET AJAX commands.
Based on the download speed, this jQuery plugin can also compute a reference internet cost that the user should pay for.
The plugin is localizable and the graphical design is highly customizable by using CSS themes and plugin options.
