Our ISP is Earthlink. We have 10M fiber connection which includes a site-to-site MPLS. I'm so confused about the speed test results of Upload generated by between my ISP and others. (Download results by all tools are almost the same at about 9.7M.)

Look, If I use , or Verizon speed test, etc, the upload speed is only about 3M. It is quite awful, isn't it? But the problem is, if I use EarthLink's own tool provided at its website:
I will get the upload speed at about 9M. That is huge difference between 3M and 9M. Can you help me figure out which number is more real? And could my ISP be cheating?
