i don't know if you know this:
there's a help site for hn customers: hughesnet support community. if you think you have slow speeds and want help from a hughes customer service rep, you're expected to run tests at testmy.net first.
actually, pretty much any post where a customer complains about speed they tell us to head over here, create an account and start running tests. it's specific: wifi turned off, hard wired to the computer, 25 mbps download, 2-3 tests at a time over the course of a day.
i'm not sure they're going to find my results with the multithread turned off acceptable. i ran a keyword search for multithread and there seems to be a perception that it doesn't provide accurate "baseline" results. they say that multithread can skew results and that it doesn't work right with satellite internet.
