uTorrent slowing down Internet

[Yoster]

For some reason, whenever I open up utorrent and download something, it slows down my Internet. A lot, I cand browse, and online games lag, it doesnt happen when Its off, but I would like it on constantly, so can anyone help me tweak the settings to fix this? Thanks.

Try Ultima's "Internet Interruption or Slow Speeds?" guide at:

Thanks, but can anyone tell me what the things like DHT do? I patched the system file and disabled peer IPs, it really helped, but not completely, but before I move on to chopping down, II would like to know, because I dont want to loose any key features.. Thanks again.

Have you read µTorrent's FAQs?

At least one of them explains DHT.

Wiki for BitTorrent/Azureus probably explains DHT better.

[Yoster]

I have tried disabling uPnP, DHT, and lowered the net max halfopen to 4. The only thing that helped was the patch, It really sped things up, but its still noticeably slow. before the patch I couldnt even wait to see how long it took to load a page, with the patch, sites that usually took 2 seconds take around 4 to 6 seconds. I have a 1 mbit DSL ISP, my last computer worked fine with it, and it was a piece of crap. I'm kind of running out of options, and I'm a major user of torrents, so this is a big problem for me, please help.

and you have set values for 1mbit in µT?

if yes, than be sure the 1mbit are NOT your downloadspeed but your UPloadspeed, cause that is what µT needs to be set after.

[Yoster]

Yes, in the speed guide I have set the connection type to 1 mbit.

[Switeck]

Speed Guide sets settings based on your UPLOAD bandwidth max, which is probably 1/4th to 1/20th of your download max!

[Yoster]

Eh, so what are you saying?

[µtorrent-Guest]

as i said, this is (probably) false.

can you Upload to others with 1MBit/s? i guess its 128 or 192 kilobits

[Yoster]

My upload numbers hang around 10 to 40 kib/s actually.

[µtorrent-Guest]

so then press CTRL+G and read what it says and choose then the correct value please!

(note: xx/1MBit is NOT the correct one)

[Yoster]

Are you saying that if I have around a 60 kb/s up speed I should choose the 56k connection?

[µtorrent-Guest]

first of all, make sure you understand what the difference between kb kB and all that is.

(thats why i prefer to write it out kilobits per second or kilobytes per second.)

µT wants a kilo or mega bits value. if you have a 1 mega bit DSL download internet connection than your ISP probably gives you an uploadspeed of 128 kilobits.

where do you get the 60kb/s value from? speed test in CTRL+G or from the contractpaper of your ISP?

Such a low speed would not be more then a crappy ISDN upload line, and you definitely should choose the xx/56k dialup value, yes.

[Yoster]

well thats what I mean, so is there something wrong with my internet or did I just make a mistake?

[Switeck]

It's also possible (even likely) that BOTH are true!

Roughly 8-10 kilobits/sec download bandwidth is needed to download at 1 KiloBYTE/sec.

So to get 100 KiloBYTES/sec file (or torrent) download speeds, you'd need 800-1000 kilobits/sec download bandwidth...roughly all you have.

But if you upload between 10-40 KiloBYTES/sec for files and torrents, then you probably have AT MOST 384 kilobits/sec upload bandwidth. And it may only be 128 kilobits/sec!

Did you disable the "IP Resolving" on the peers tab? That was what caused my weird internet problems when I first started using uTorrent.

[Switeck]

Generally, if disabling the "IP Resolving" on the peers tab helps...you have crappy networking hardware or software on your end.

[Yoster]

I disabled IP resolving, and when I tried a test at DSL reports, I got 304 upload kbits/s and 1293Kb/s download speed.I switched my connection to 256k and my internet is now back to normal, but out of 4 seeds, 1 is uploading and the rest are queud, I am not connected to anyone on those 3, is that the reason?

[µtorrent-Guest]

1 out of 4 is normal giving the low upload values of most dsl lines

[Yoster]

well, if thats so, and leeching is the non seeding of torrents, whats the difference between keeping them and making room for others?

[Switeck]

Yoster,

You may be able to use xx/384k -- but you probably should reduce the upload speed after selecting that to 30 KiloBYTES/sec (it defaults to 35).

[Yoster]

Ok, I really dont care about my up speeds, its the down that I want.

[µtorrent-Guest]

it doesn't matter what YOU care about

for the BT protocol to fucntion in a way that gives you good downspeeds it's the upspeed the clients care about.

screw the uploadspeed and you subsequently screw your downloadspeed you care so much about

Edit: and with respect to your former question: µT will cycle thru the queued torrents. so it is essential to not remove them. if you use a private tracker with ratio enforcement keeping them in the queue instead of deleting them can be essential for you to prevent being banned or have your downloadability revoked untill you seed the stuff you downloaded.

[Yoster]

Ok, whatever, I think this is good, I just started a torrent with 10 seeds and 54 peers and am getting a down speed ranging from 20 to 50, with an up speed of 15 to 20. I re enabled DHT since it didnt help, how do I enable the peer I resolving? If I right click on peers nothing pops up. Update, download speeds soaring over 80
