Configure ktorrent for fastest downloads

Hi Eric,

Curious what you're paying for that these days from Cox Business.

I used to work for them some ~20yr ago, so had it for many years, but found
it not worth the cost over time.  I moved to residential, which was fine,
other than the every 4 years or so I'd have to call them to come replace
feeder cable to my house from cable suckage (heat/metal
expansion/contraction, not literal), and have to wait a day to get a tech
here.  Upstream isn't so important unless you're trying to be the next
piratebay top 10 seeder, so I'm all for cost savings, thus moving to
centurylink the past year.

Which by the way, I rather hate lec/telco's by nature, so this was
difficult.  My doing so was purely a financial decision.  Shame Cox
implemented data caps, I never minded paying a bit more for better service,
but when randomly 10-20 dollars higher than normal, I got angry.

Side note - business modem usage of RF spectrum isn't any different from
residential users, you only get a different modem config file that allows
things like tcp/25 and 80 ports, more synchronous bandwidth as mentioned,
and that's really it.  Coming from someone working with cable modems circa
'99 pre-docsis, their hype isn't all that besides 24/7 physical support,
more synchronous bandwidth, and better peering (ie. local peering vs.
California egress, some ~20ms).  Cox does however in general do a good job
of managing bandwidth at the node level, residential or business, to keep
things copacetic in either regard.
