This tool allows you to calculate how quickly a page will download for people using various modem connections.

Used in combination with the HTML Compressor, you can make sure your pages load as quickly as possible for all visitors.

Go to the demo (real versions are password protected) and check the 'File Control' module of the control panel to calculate download speed/time.

The software is free for all hosting clients and can be installed under any domain (via the control panel).
