How This Data Was Generated
This chart shows the result of downloading the chosen URL many times in succession,
with a short wait (e.g. 3.0 seconds) between each download,
to assure that the HTTP connection was closed.
The downloads were done without use of any cache.
The chart shows variations in the speed of download of every component of the page,
and variations in the total page download and rendering time,
as a function of activity on the Web.
Normally there are 10%-15% variations in these timings.
Note: This applet may not behave correctly if you are not using the standard IE version of the JRE.

Chart Explanations
This chart shows the complete, detailed timings for playback of a script that references a number of different URLs.
Each stack slice of data shows the time for each page component (*GIF, *CSS, etc).
Hover your mouse over a stack slice on the picture to read details about that particular download. |
The Green line shows the average total time for all events. |
The Yellow line shows the value that is 25% below the average. |
The Red line shows the value that is 25% above the average. (The Red line may be omitted if it would be above the topmost chart element. |
Click on any stack slice to see that event fully displayed.) |
Return to the original display by clicking on the icon at the lower left-hand side. |
If the chart does not fit on one page you can click on to scroll the chart one bar to the left, or to scroll the chart one bar to the right. |
You can also click on to scroll the chart one quarter way to the left, or to scroll the chart one quarter way to the right. |
Hover over the left hand axis (the vertical axis) to see the time value. Times are expressed in milliseconds throughout. |
