Proving Gig Speed

[Chris Gross <CGross () ninestarconnect com>]

I'm curious what people here have found as a good standard for providing solid speedtest results to customers. All our 
techs have Dell laptops of various models, but we always hit 100% CPU when doing a Ookla speedtest for a server we have 
on site. So then if you have a customer paying for 600M or 1000M symmetric, they get mad and demand you prove it's full 
speed. At that point we have to roll out different people with JDSU's to test and prove it's functional where a Ookla 
result would substitute fine if we didn't have crummy laptops possibly. Even though from what I can see on some google 
results, we exceed the standards several providers call for.

Most of these complaints come from the typical "power" internet user of course that never actually uses more than 50M 
sustained paying for a residential connection, so running a circuit test on each turn up is uncalled for.

Anyone have any suggestions of the requirements (CPU/RAM/etc) for a laptop that can actually do symmetric gig, a rugged 
small inexpensive device we can roll with instead to prove, or any other weird solution involving ritual sacrifice that 
isn't too offensive to the eyes?
