Would you like to know how long it takes to load a webpage? This program will measure the time for you. Enter the URL to be measured and watch the top of the window.

The StopWatch can only measure websites that can be displayed in a frame. Some websites use javascript to break out of frames. This is not a StopWatch bug.

Enter the URL to be measured:

Or click on one of these links:
[Google] [Yahoo] [Altavista] [Excite] []
[Microsoft] [ZDnet] [IMDB] [Tucows]

Tip: to reload a page and bypass the cache of your browser:
Internet Explorer: Hold the Control key and click the Refresh button on the toolbar.
Mozilla, Firefox, Netscape Navigator: Hold down the Shift key and click the Reload button on the navigation toolbar.
Safari: Hold down the Shift key and click the Reload toolbar button.

How does it work?
The stopwatch is a small Javascript that runs on your computer (not the Numion server). It measures the time between the moment your browser starts to load the URL and when the browser signals that it has finished ("Done" in the status bar). The measurement therefore includes fetching and interpreting all HTML (including frames), images, and Javascripts. It does not include content that is handled by plugins. If the page is in the cache then the stopwatch will measure the faster loading time (see tip above). The accuracy is the accuracy of the Javascript timer, on most systems 10 milliseconds.
