I just recorded a 3150 kbps download from the New Jersey server of DSL Reports speed test. That's close to my best speed ever even though I allegedly have 4 megs. More often than not, I don't get any faster results than I had with the 3 meg connection (2500 kbps or so.) Yet the DSL Reports distribution for the Comcast domain shows the highest concentration right around 38-3900. I wonder who's getting those speeds?
