Time Checker.
Transfer rates to check: Here you set the transfer rates. You
can customize the simulated transfer rates of the program. Values are
given in bytes/sec. Current standard modems, for example, offer a speed
of 57600 bytes/sec. Using the buttons on the right you can add, delete,
move up or move down the transfer rates. The specifications are made in
Byte/s. To do so, select the desired transfer rate and click the corresponding
button.
Embedded links: Define the HTML tags of the intergrated links.
This is to specify the HTML sections that are to be checked, e. g. tables
<table> or images <img>. To add further HTML tags or delete
tags from the list, click the corresponding button.
Click OK, to save your settings and to close the Options dialog box.
In the URL field in the toolbar, enter the URL or file name to be checked. Make sure to include "file://" for file names.
Click Go to start checking the loading time.
The Load Time Checker now determines the loading time for all the elements of the page (e.g. images). The Load Time Checker lists the expected loading time for each checked file at different transfer rates. Under Total at the bottom of the report window, the total loading time of the website is displayed.
If
you wish to save the report, click the Save
report 
button.
