Bandwidth Speed Test Site List

Note: My tests showed results varied by which test service you used (20%), the media (fiber vs coax [I didn't test DSL]) (50% for some test services), depending on what computer you used (800 MHz PC vs 1GHz Mac) 60%, time of day (3-5%), and which browser you used.
e.g. IE produced the same results except for use with on a Mac where it was 70% slower.

Note: Speakeasy consistently found my Optimum Online (cable) download speed about 20% faster than Verizon FiOS (fiber), while Broadstar and found it about 15% slower. Both were around 10 Mbps download.
On the other-hand upload speeds were 20% slower for Optimum Online with Speakeasy while cable and fiber were the same for Broadstar and; about 1.7 Mbps.

Above tests were done on a Macintosh with OS X 10.4 and a 1 GHz G4 powerbook.
Tests done on a PC with a fresh copy of Windows 2000 on a Dell 800 MHz Pentium III produced speeds 60% slower except for SpeakEasy over verizon fiber which had speed similar to those on the Mac. SpeakEasy over cable service showed speeds 50% slower on the Dell than on the Mac.

The browser used Internet Explorer (IE), Firefox or Safari (Mac) didn't make any difference except for IE on a Mac with where it was 70% slower.

at&t/SBC gave results between speakeasy and test on cable (10 Mbps) and very low results (1-2 Mbps) on Verizon fiber.
