I recently upgraded from 6 mbps to 50 mbps. I want to run some stress tests, but don't know how. I'd like to do something akin to downloading large files, but it has to be perpetual. I want to see how the bandwidth is being distributed across multiple computers and devices.
 
fire up a free/small linux instance on amazon ec2. or google's new cloud compute, whatever it's called, same thing. just takes a minute. install iperf on virtual machine. install iperf on a computer attached to your network. have at it!
 
Id say that for what you're wanting to do, a simple speedtest.net test with a local mirror should suffice.
 
If you want to see how your home router load balances the network to multiple devices why not just hook up an iperf server on the other side of your router?

If you want to test everything you can do what tacos4me said but just make sure the client parameters include a longer period of time to be sort of "perpetual". The "-t" defines the length of time in seconds the test lasts. The "-i" is increments in seconds that the iperf program reports back to you.

iperf -c X.X.X.X -t 20 -i 1 -f m

Even if you got this setup on an external server your speed test will only be accurate to that specific server. You could get a wildly different result by using a local server versus one on the other side of the country under load plus any number of other influencing parameters.
