OK, I guess that certainly means a lot if you want outgoing "upload"
bandwidth. I hadn't realized how limited residential service is in
that regard.
If all you want is incoming "download" bandwidth, and don't need
guarantees, it's a big waste. My standard RR service gives me up to
6.4mbps (800KB/s), which is more than four times what a T1 provides,
and it's usually at least 3mbps.
I can get a 60 megabyte file in 75 seconds (60 / 0.8kB/s), though it
might take as much as 150, but it's always going to take 320 seconds
for a T1 (60*8/1.5mbps).
Or am I still missing something?
Does "synchronous" mean they buffer if the backbone is tied up, or
are you still at the mercy of the backbone and stuff beyond their
control?
A lot of times downloads are limited by the server anyway, but I'd
like to have the 600mbps download bandwidth Bruce is claiming. That
is about 400 times what a T1 does.
