There are a number of places available to test your FiOS connection to make sure you're getting the most of your service. However, with the high-bandwidth that Verizon FiOS brings to your home, you should be aware not all speedtests are created equally. They are flash-based or java-based. It is suggested you use a java-based speed test for more accurate results, as flash-based tests may be subject to network compression. Results can also be impacted by network conditions anywhere between you and the test server. If you are given a choice of speedtest locations, choose the location nearest you.
• DSL Reports. These may be useful because they can be logged to show history.
• Java-based Visualware delivers consistent socket-to-socket results for many people. Choose the location nearest you.
• Java-based Verizon FiOS test keeps traffic on the Verizon network, so it may isolate non-Verizon network conditions from your results.
• Argonne National Laboratory NDT is a Web100 java-based test with a Gigabit ethernet connection, so there should be plenty of oomph behind it in most circumstances.
• Optimum Online FTP speed test downloads a 64MB file. View the transfer rate between 30-60% complete. Does not test upload.
Don't confuse the difference between bits per second (bps) and bytes per second (Bps). Your service connection is typically specified with two numbers like 10/2, 20/5, 25/15 and the like. The first number is download speed, the second number is upload speed. 20/5 service delivers 20 Mbps download and 5 Mbps upload. Divide the numbers by 8 to derive 2.5 MBps and 625 KBps (0.625 MBps).
