/* How does it work? The script generates a variable amount of random data
* sends it to the client and measures the time taken for transmission. The
* bandwidth is then calculated from the time using a simple algorithm.
*
* WARNING: This script can bog down your server - as absolutely NO
* optimization was used.
*
*
* This script is best run on the Zend PHP Engine, with Zend Optimizer.
* Any improvement in performance is not guaranteed with other
* PHP Engines.
*
* History:
* 0.9 - First public release
* 0.91 - Reduced the size of the timing code
* 0.92 - Reduced the size of the timing code even more
* Forecast:
* 0.921a - Adding a smaller test before the main to make results more accurate and to adjust test data according to first results
* 1.0 - Looking to adding optimization code
* 1.1 - Adding template support
* 1.2 - Adding web-based administration
