The formula should be something like
A T1 a synchronous connection (same speed both ways) of 1.54 mbs
(megabits/sec) or 1540 kbs (kilobits/sec). Divide by 8 and you get 192.5
KiloBytes/sec. There is some packet overhead in here that is not being
accounted for.
At this rate you could service 19.25 10K pages per second (assuming no sub
elements). Bear in mind however that your client's connection speed will
affect this. If a client is on a dialup at 56K then they are pulling data
much slower than your max speed, allowing you to service more clients
consecutively at the slower rate.
You also can yield huge benefits from client side cache if you build the
pages properly.
The below spec of 5000 pages/day pre domain is the same as (if you average
it across the whole day and do not account for peaks and valleys):
5000*50/day
250,000/day
10,417/hour
173/min
2.8/sec
(as stated below). A T1 is overkill for this, however, we usually estimate
across a 6 hour day to account for peaks and valleys. So the formula of:
PageViewsPerDay/24/60/60 becomes PageViewsPerDay/4/60/60 which up's the
required bandwidth to
5000*50/day
250,000/day
62,500/hour
1042/min
17.3/sec
which is still well within the limits of a T1 or something of comperable
speed.

No, 10K per hour is 2.7 per second. 173is per minute.
But most pages are a hell of a lot larger then 5k.
