What are some tools to test bandwidth perfomance? I've used iperf, but are there other tools or ways to generate traffic for testing purposes to see a links maximum capacity? Especially greater than a 100mb.

Realistically, you will need commercial hardware/software to do this properly. Smartbits, Shomiti, are two examples (Shomiti is less than user friendly, but the thing can do almost anything)

If Governments really want us to behave like civilized human beings, they should give serious consideration towards setting a better example: Ruling by force, rather than consensus; the unrestrained application of unjust laws (which the victim-populations were never allowed input on in the first place); the State policy of justice only for the rich and elected; the intentional abuse and occassionally destruction of entire populations merely to distract an already apathetic and numb electorate... This type of demogoguery must surely wipe out the fascist United States as surely as it wiped out the fascist Union of Soviet Socialist Republics.

The views expressed here are mine, and NOT those of my employers, associates, or others. Besides, if it *were* the opinion of all of those people, I doubt there would be a problem to bitch about in the first place... --------------------------------------------------------------------
