Speed Test FAQs
Factors that can slow you down.
What is Ping, Jitter, Download, and Upload?
  • Ping is a good tool to see if another host is reachable and if there are delays. Ping times do not test Speed (Bandwidth). If you have high Ping times, optimize your connection!
  • Jitter tests the performance and speed of a network over a period of time. If you have high Jitter times, optimize your connection!
  • Download is how fast you can pull data from the server to you. Downloading is necessary for things like streaming movies or TV using services like CenturyLink Stream.
  • Upload is how fast you send data to others. Uploading is necessary for things like sending big files, video-chat, or posting pictures to facebook.
  • Speed (Bandwidth) vs. Latency
    Latency is how long it takes data to travel between its source and destination.
    Speed (Bandwidth) is how much data can travel between its source and destination.
