Check out net-analyzer/ttcp and net-misc/iperf You could also probably "roll your own" test by using netcat to transfer /dev/zero from one machine to another or something like that. > Background: We sold our house & moved.

I don't have Comcast but often ISPs will host a speed test server inside their network, so you can ensure the speeds you're seeing are not being limited by normal Internet slowdown issues outside of their system. To take a page out of the generic ISP tech support, I would try plugging your computer directly into the cable modem and seeing what kind of speeds you get then, to eliminate any outside factors. If you're using your own router, I would check to ensure it is fast enough to handle that kind of speed. If it has Gigabit ethernet ports that is usually a good sign. If it only has 10/100 then you might wind up replacing it with something more modern.
