What is SiteSpeed?

SiteSpeed is a program you can add to your website. It will measure how long it takes your visitors to download a page, automatically and unobtrusively. Part of the measurement system is a small icon that becomes visible on your page, the SiteSpeed icon.

When a user visits your page then a timer will start ticking on the computer of the user, and the user will see the static SiteSpeed icon. The timer will stop when the entire webpage has been loaded by the user's browser. The elapsed time is calculated and stored in a logfile on your server.

If everything is in order (the SiteSpeed program on your server has stored the measurement) then the icon will start animating. You can click the icon to see your statistics.

If something is wrong (SiteSpeed could not save the measurement in the logfile) then the icon will blink "error" in red. Most likely the scripts do not have write-access. See the Installation Instructions for more information.
