Re: Should i worry?

I stand corrected on the 27mbit I thought QAM64 doubled QAM16. So that would put at nearer 60%, and yes the % will have variances as its only an average figure but my point was if you got 10mbit users on a 18mbit channel then a single user can swing the utilisation by 60%, thats just scary.

Now you have corrected me on the QAM64 I now feel the minimal that should be used is 2xQAM16 or 2xQAM64. They seem to be realising that the same issue on the downstream isnt ideal (hence them adding downstreams) but are prepared to let the upstream suffer.

Regardless of how many torrent I still feel a user uploading out of 200 is more than a remote possibility, that comment had no reference to torrent users. People do other things like speedtests, uploading videos, pictures, streaming that can max out upstream bandwidth. We even have the trend now of people starting hosting companies on their cable connections because VM for some bizzare reason didnt add anything to their t&c's forbidding non gaming servers.

I agree with you on reducing users, but that is in my view is less effective than increasing pipe size. Also evident is that some areas clearly havent had users reduced much with 100s of users sharing upstream channels. That is not a low number. I would consider something like 10 users on my channel been low not 200. Better to have 100 sharing 54mbit than say 20 sharing 18mbit.
