On average, I personally could be satisfied with a megabit, but it's a real pain to download gigabyte-class software updates at that speed. If it takes me literally days to download a game's beta versions, any comments I might have will be stale by the time they can be heard, and in the meantime my other uses of the internet have been seriously impaired. It's much more useful if I can download the same data in an hour, and spend the remaining time evaluating. So throughput is indeed a factor in response time, once the size of the response is sufficiently large. Occasionally, of course, practically everyone in the country wants to tune into coverage of some event at the same time. More commonly, they simply get home from work and school at the same time every day. That breaks the assumptions behind pure statistical multiplexing, and requires a greater provisioning factor. - Jonathan Morton --001a11479aa4f6267205602ce396 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable
