One of the most popular ways to test Internet connection speeds is to use speedtest.net. The problem with using a site like this is that providers sometimes have a feature that increases the bandwidth for the initial part of the download. This allows for faster downloads of smaller files. Unfortunately this really messes with speed tests. For instance, I’m now getting 15 megabits per second down, but the tests are telling me that I’m getting 28-30 megabits per second. This would be fabulous if I got it, but I don’t. A more accurate test is to download a large file from a fast host. In my case, I download stuff from Apple and get about 2 megabytes per second which is 16 megabits per second. This is more in line with what I’d expect.
