Internet metrics

["Schmiedt, Jamie" <jamie.schmiedt () lodgenet com>]

I am looking for websites that deal with bandwidth and performance metrics
as they pertain to the Internet?  Anything and everything goes.  I need to
get a snapshot in time of things like "the average speed of the Internet",
the average size of e-mail messages, the average size of a web page, peering
points and hosting facilities, current bottlenecks be they hardware,
software or networks.

Any cool links for this sorta info will be greatly appreciated.

Thanks in advance
