http://speed.cloudalize.com will redirect you to a speedtest site in your geographical location and measure your speed and latency to our datacenter (if possible use Chrome - do not use Internet Explorer).
After the test is complete you will see 4 values. Download, Upload, Latency and Jitter. Download and Upload are in Mbit/s (megabit). Latency and Jitter are in ms (milliseconds). Latency is the average ping speed. Jitter is the deviation of latency. When Jitter is unstable it will have a negative effect on your experience.
If your download and upload speed is > 10Mbit you have a decent enough speed.
If your latency is < 60ms you have a strong latency, if it is between 60 and 150ms you have a weak latency, if it is > 150ms you have a poor latency.
If your jitter is < 10ms and it is stable you have a decent jitter.
