Line Speed Comparison Chart
About Broadband: Download line speed for Broadband (DSL, cable) ranges from
512 Kbps all the way to 10,240 Kbps depending upon network utilization. Upload
line speed is usually lower (128 to 768 Kbps).
Some newer HDSL services can reach up to 5,120 Kbps with upload speeds between 128 and 512 Kbps.
Modem users:
Even when using a 56K modem, your speed may never attain 56 Kbps. In the
US, the FCC may limit phone bandwidth to prevent interference between phone lines.
If your line speed is over 44 Kbps, you are in the zone.
ISDN, DSL (ADSL/SDSL) or T1 subscribers:
Your line speed is normally guaranteed since you are purchasing dedicated
bandwidth but if your line speed is consistently under 85% of the level you
purchased, you might want to contact your network administrator or ISP.
Cable Modem/FiOS subscribers:
Cable modem/FiOS bandwidth is normally shared across all users on the same
network or sub-network and the advertised bandwidth is a theoretical average based on the fact that not everyone will use the network at the same time. Although you normally enjoy T1-like speeds or better, you could also find yourself surfing the Low-Broadband doldrums during peak times.
If you can live with limited upload speed (asymmetric bandwidth), no static IP and limited choices (Cable Companies have distribution area monopoly), cable service is the fattest pipe currently available for residential internet service.
About this test:
Remember, this speed test is not absolute. Your line speed will vary based on your ISP network saturation level and/or according to the route the internet chose for your data - or if you are streaming music or video while performing this test ;-)
This test uses a 200 KB binary file for greater accuracy and compensates for network overhead.
The speed test conundrum is that it is faster to transfer one large file than
several small ones but small files transfer in such short times that it becomes
difficult to measure. We found that 200 KB (~204,800 bytes) seems to be a happy compromise that is both accurate and does not make modem users wait too long for results (maximum wait is ~30s at 56Kbps).
