.... lobits = 56,000 bits. To convert the file
size to bits, you should first convert it to bytes (84 kilobytes
= 84,000 bytes). Then convert the bytes to bits by multiplying
84,000 by 8 (1 byte = 8 bits), which results in 672,000 bits.

Divide the file size (672,000 bits) by the connection speed
(56,000 bits per second). The bits cancel out, and the results
is 12 seconds. This is the amount of time it will theoretically
take to download the Web page.

Remember that the figure derived from these four steps, is a
theoretical measurement. It does not consider certain factors,
such as the fact that 56 Kbps modems rarely operate above 50
Kbps. Nor does it consider network overhead, such as noisy phone
lines, or network congestion.

Therefore the best way to determine how quickly users can
download your web sites pages, is to test them in a real-world
setting. For example, test your web site by accessing it through
a dial-up (i.e., telephone) connection. That method will give
you a much more reliable estimate.

Factors that Affect the Download Time of Your Site
1. Optimizing Images - this refers to the process of striking a
balance between file size and image quality. Your images should
not be too large or have too many on your web site. This will cause
your pages too long to come up in the users browser and they'll
lose their patience.

Of course, if you images are too poor (too small, or with too
low of a resolution), your site will be unattractive and it
won't matter how quickly the site loads. You need to seek the
perfect balance between size and quality.

2. File Formats - There are two main types of images on the Web:
GIF (Graphics Interchange Format) and JPEG (Joint Photographic
Experts Group) files. Each format compresses fil....[MORE]
