Dreamweaver includes a Download Indicator on the status bar at the bottom of the Document window.

The Download Indicator displays the file size of the page, followed by the seconds it will take to download at a particular modem speed. It is generally a good idea to keep the file size to around 30K at the most.

You can set the modem speed for the download time in Preferences. If you are creating a Web page for the general audience, it's a good idea to set the modem speed to 28.8 Kbps.

To set modem speed:

1	Choose Edit > Preferences, and then select Status Bar.
2	Click the Arrow button next to Connection Speed to select a modem speed.
3	Click OK.
