How to Calculate and Speed-Up the Download Time of Your Web Site

Written by Herman Drost

Have you ever experiencedrepparttar frustration of waiting for a web site to download, then giving up and moving on to another? This is because most web users lose their attention after 10 seconds. If your site takes longer than this to load, you will be losing many visitors. This means thatrepparttar 131884 web designer must use images sparingly and choose file formats carefully.

How to Calculate Download Time 1. Checkrepparttar 131885 size ofrepparttar 131886 HTML file and any associated images, files or programs. You can do this by right clicking onrepparttar 131887 file or image and reading its properties. For example, you may have a page that consists of 10 files, for a total of 84 kilobytes (KB). For a more extensive explanation for calculating file sizes, see my previous article - "How Much Hosting Space Do You Need?" (

2. Determinerepparttar 131888 speed of your network connection. Some ofrepparttar 131889 more common speeds are: 14.4 Kbps (kilobits per second) - slow modem speed 28.8 Kbps - typical modem speed for some users. 56 Kbps - typical modem speed for most users with a dial-up connection. 1.544 Mbps (million bits per second) - full T1, enterprise grade network line (equivalent of 24 phone circuits).

3. For this example, we will use 56 kilobits per second (Kbps). The connection speed and file size must be converted to a common unit of measure for division: either bytes or bits. Remember that 1 byte equals 8 bits. The connection speed is already defined in bits: 56 kilobits = 56,000 bits. To convertrepparttar 131890 file size to bits, you should first convert it to bytes (84 kilobytes = 84,000 bytes). Then convertrepparttar 131891 bytes to bits by multiplying 84,000 by 8 (1 byte = 8 bits), which results in 672,000 bits.

Dividerepparttar 131892 file size (672,000 bits) byrepparttar 131893 connection speed (56,000 bits per second). The bits cancel out, andrepparttar 131894 results is 12 seconds. This isrepparttar 131895 amount of time it will theoretically take to downloadrepparttar 131896 Web page.

Remember thatrepparttar 131897 figure derived from these four steps, is a theoretical measurement. It does not consider certain factors, such asrepparttar 131898 fact that 56 Kbps modems rarely operate above 50 Kbps. Nor does it consider network overhead, such as noisy phone lines, or network congestion.

Thereforerepparttar 131899 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 Affectrepparttar 131900 Download Time of Your Site 1. Optimizing Images - this refers torepparttar 131901 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 inrepparttar 131902 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 quicklyrepparttar 131903 site loads. You need to seekrepparttar 131904 perfect balance between size and quality.
