An American depositary receipt (ADR, and sometimes spelled depository) is a negotiable security that represents securities of a non-U.S. company that trades in the U.S. financial markets. Shares of many non-U.S. companies trade on U.S. stock exchanges through ADRs, which are denominated and pay dividends in U.S. dollars and may be traded like regular shares of stock.
At 57 Mb/s, the download speed was great; however, the upload speed was a mere 0.17 Mb/s, which is pretty much unusable. In fact, I had to re-run the test several times, as occasionally, the upload portion of the test would get stuck and never complete.
Beware that 1080p youtube requires only 5-6Mbit REAL download speed and that torrents are heavily multithreaded. My evidence that speedof.me is reliable is that everytime I lag in games, speedof.me would show a slow speed whereas speedtest may show a high speed which is obviously the result of multithreading. Also when it fails to buffer properly in twitch/youtube, speedof.me displays the REAL speed whereas speedtests in general inflate this number by gross proportions.
