I have little faith using online speed tests from sites such as DSLreports and especialy TimeWarners internal test site.
Linux has a simple bandwidth test program called iperf which can measure both udp and tcp throughput, as well as latency and jitter. You just have to have someone else running iperf too, and of course your measurements will be limited to the slowest part of the link between you. If the other guy has a slow connection then you'll get a low number between him and you. But if it's a site you often use then you've got direct measurement of performance between those sites. Find several friends running iperf and your link performace is probably the highest number you get from such measurements. In the past I've run it from cron with the output piped to either a log file or mail to collect statistics.
