An important question: is this 1 Mbps, or 1 MBps? “B” is for “byte,” which is eight bits-with-a-“b”; ISPs are inconsistent about providing these numbers, but usually quote performance in bits. FWIW, I have found that downloading is the most demanding thing I do, and I frequently exceed 1Mb/s, but rarely approach 1MB/s, even though my service allows this. I attribute this to the source, rather than my ISP, although my cable performance can be degraded by bandwidth sharing.
