All: I am having some speedtest results that are difficult to interpret. I am a small WISP multi-homed with Cogent and Level 3 in Houston, TX. I am running BGP with each with 100 Mbps+ on each link. Some of my customers have begun complaining that they are not getting the proper speeds. They are using speedtest.net and/or speakeasy.net to test the results. My network is Mikrotik based and as such, I have access to Mikrotik's built-in bandwidth testing. With a laptop on site, running against speedtest.net (which kicked me over to the Comcast speedtest server instance) I can only get 4 Mbps up and 1.5 Mbps down. That is consistent on their desktops too. We eliminated their routing equipment and other consumers of the bandwidth and tested and got similar results. But when we run the Mikrotik bandwidth tests (even to off-net Mikrotik devices in Hawaii and Mission, TX) we get 25+ Mbps synchronous. We have run traceroutes to various traceroute servers and they go through Cogent and/or Level 3. For the most part it does not seem to matter which path it takes, the bandwidth seems to be about the same going both routes. When we run the laptop-based btest.exe against Mikrotik bandwidth test servers, the laptop got significantly better results (14 Mbps) , but not 25+ Mbps. It is almost like there is a Java based problem with speedtest.net. Thoughts? Thanks, Lorell Hathcock
