"Speed Testing" is a common thing end-users do to see what kind of connection they have on the Internet. However, Speed Tests that are hosted on the public Internet are not always of high quality. This is because the speed test often does not have accurate servers or systems, and also the number of hops from your computer to the speed test server can dramatically affect the results. Usually these speed tests do not handle parallel systems.
There are several ways to "Test" your speed, with varying accuracy and quality.
- Iperf Speed Testing. This is a highly reliable way to do an accurate speed test, however, it requires some configuration and knowledge. If you want to do speed debugging, then please click on the link. All performance testing done by our Network Operation Center is performed using this testing. This is the same speed testing ACD uses internally, and is the general debugging mechanism used by ACD to debug all connection bandwidth issues.
- http://www.speedtest.net and http://speedtest.acd.net. This is a browser based interface. No browser based interface is going to be highly accurate, especially at high speeds, including these common consumer speed tests. However, it provides results quickly. The advantage with browser based speed tests is that they work through firewalls. However, they do not work accurately, primarily because they a) utilize only one udp stream b) and the tests operate for only a very short period of time, that do not allow the TCP windows to adjust to the speed request. These speed tests are not accurate for:
- any bonded types of connections, or link sharing technology.
- Bonded T1 lines
- Bonded ADSL2+
- G.shdsl.bis or [http://www.acd.net/efm.cfm Ethernet First Mile or UltraSpeed Services}
