Monitor Net Traffic

[drew einhorn]

Actually the bottle neck can be anywhere between you and the server.

the end points
   between you and your ISP, or
   between the server and their ISP

But it can also be between
   your ISP and your ISP's service provider(s)

Or anywhere in between.

Small pipes are some multiple of 1.5 mega bits/second.

Bigger pipes are some multiple of 45 mega bits/second.

Etc.

divide the size of a pipe by the number of simultaneous users sharing the
pipe is a good estimate of what you will get.

There are lots of ways this can get more complicated

    a service provider probably has multiple pipes
    Sometimes some kinds of traffic are given priority of other types of
traffic.
    Yada, Yada, Yada,

If your router, firewall, pc, (whatever).

Some box that:

   handles all the traffic to and from your ISP,
   speaks (SNMP)

There are applications,

    For example, net-snmp http://www.net-snmp.org/

that allow just about any operating system to speak SNMP and provide receive
and transmit statistics on all its network interfaces.

MRTG http://oss.oetiker.ch/mrtg/ can plot the average bandwidth in both
directions at intervals over periods between 5 minutes, and 1 day.

Look for the highest sustained peaks on the graphs.
