Interpreting Your Speed Test Results:
Download is a measure of how fast your connection delivers content to your computer or local area network. With many web pages and basic email programs, you will have difficulty noticing the difference between say a 1,500 kilobits per second (kbps) download and a 3,000 kbps download. However, for large files or a connection used by a large number of people a 1,500 kbps difference in download speed can be the difference between a quality broadband experience and a frustrating one.
Typical rated speeds vary depending on your type of Internet connection. Dial-up users can get up to 54 kbps but typical connections are in the 40's. Cable modem users can expect from 1,000 to 6,000 Kbps, the maximum rate may be capped by the cable company. DSL users get from 256 kbps to 2,000 kbps depending on the level of service you have purchased. Note: These are the speeds for download only; speeds for uploads are usually lower.
Upload is the measure of how fast content is delivered from your computer or local area network to others on the Internet. To achieve optimal delivery their download speed must be at least as fast as your upload speed. This is very important for applications like VoIP, email, on-line gaming and other interactive programs. Upload speed is even more important if you are operating an email, web or file server at your location. Many broadband providers, especially cable and phone companies, see broadband as another broadcast medium ("one to many") and don't tailor their connections for optimal upload speeds ("many to many"). The bottom line is that it's important not to underestimate the importance of upload speeds, especially if you are a "contributor" of data to the rest of the Internet.
In general, if your upload speed is at least 80% of the rated connection speed, you're receiving acceptable performance. Of course, if you're sharing a connection, you can't expect to get the full bandwidth.
Here are some guidelines for upload speeds; note that download speeds are usually higher than upload speeds. Dial-up users can expect 40 kbps or lower depending on the quality of phone lines and modems.
Cable modem providers often cap their customer's upload bandwidth at 128, 256 or 512 kbps. If they didn't speeds could be as fast as 1,000 kbps. DSL users can expect 64 Kb/s to 1,500 Kb/s depending on the level of service purchased.
Remember that your bandwidth measurement can vary somewhat from minute to minute, depending on traffic at your ISP and on the Internet. It's a good idea to measure your bandwidth several times, across several days, before drawing any conclusions.
