How is Edge So Fast? I have the BLU STUDIO 5.5 on T-Mobile, however its not a T-Mobile device. I only get Edge. It's pretty slow for video watching. However, it loads sites in less than 2 seconds. Sometimes less than 1. How is that possible? On 4G sometimes I didn't get that, especially when I was throttled after using my complementary LTE data.
Some sites which you recently visited are stored on your browser memory as cache and cookies, so when on slow speed data connection it comes up as a plus point because sites load in a second.

Try this: clear cookies and cache and now try to load the same site on edge. It will take long!
