Utorrent Slows Internet speed

It would seem that your problem has been solved after lowering the upload... Use the Speed Guide to set the correct limit. If you still want to patch (even though it's not necessary if you're no longer having any problems), then here it is:

Reboot after patching, and increase your net.max_halfopen as well to about 80% of the number you set in the patch.

LOLOL @ Mighty Buzz LOL nice......

@ adrangers:

capping upload (see Firon's post for numbers) is the easiest way to smooth bting and CFosSpeed is like the cherry on top, if you happen to be the possessor of a usb modem I feel for you, upload saturation is MUCH worse for those things....I had the misfortune of having one back in the day....they sucked then and they suck now....

Adrangers - Do you connect to your cable / dsl modem directly, or do you have some sort of router & nat firewall? If the latter, it probably has an option to turn on Quality of Service (QoS). It is fairly easy to use that to put web (HTTP) traffic at a higher priority than bittorrent or other P2P traffic. This will solve your problem.

Oooooh, get cFosSpeed. It's like the lovechild of QoS and renice! You probably don't know much about either of those though so take my word for it that it kicks much in the way of ass.

That's an interesting product, I'd never seen it before. Though I don't know that it would be any more effective than normal QoS for adrangers. By "slow internet" I assume he means HTTP, in which case just using QoS with a low priority on bittorrent would take care of things. HTTP requests and responses get bumped to the front, problem solved.

cFos does look interesting for anyone who does a lot of high-bandwidth dl/ul in a single protocol. And I don't know if it recognizes the acks for bittorrent itself, but if it did it would have the potential to speed up your bt dls. Plus the idea of dedicated ack traffic shaping makes me think of the hilarious optimistic ack attack.

cFos is basically a software QoS manager, and would be especially helpful if adrangers' modem/router didn't include a built-in QoS manager. I'm pretty sure it supports BitTorrent =P

(I've thought about using cFosSpeed, but my computer isn't the only one on the network that uses BitTorrent, so using it would be pointless... too bad my stupid router doesn't have a QoS manager =T)
