utorrent slowing down my broadband wtf !

MooseJam

I use utorrent and it really slows down internet use for some reason, even if it's only downloading at 5kb/s, page loading takes alot longer, is this a well known issue ? anything I can do besides turning it off ?

Is there a limit on your upload speed?

MooseJam

yeah it's 10 k up, it's not the amount of traffic that slows it down it must just be something about the way the program works- it's strange

I've found the same with azureus and bitcomet too. They do sometimes make a very large number of connections even when the download rate is quite low which might be a factor.

Windows has limits on the max number of new connections allowed per second. Also broadband routers have a limit too on the number of concurrent connections they can handle.

These numbers generally aren't advertised as manufacturers don't expect people to hit these limits. But run an aggressive P2P or torrent client and you can find yourself hitting this wall.

For my own experience I know that Limewire and Azureus do hit the max number of allowed new connection attempts limit from time to time on windows. Shows up in the event log as TCP/IP error or warning.

Also my last broadband router would sometimes not allow me to connect. A few hair pulling and WTF moments trying to understand it. As a second computer is happily connected. Seems the router simply didn't have a single free connection available. (Got a new router)

Generally speaking limiting download to below the max on your line and limiting upload to below the max on your line should sort you out nicely

Are you using Vista? My internet was unusable when I used uTorrent in Vista. Maybe try "netsh tcp set global autotuninglevel=disabled" from the command line if you are using Vista.

MooseJam

yah am using vista, what will netsh tcp set global autotuninglevel=disabled do ? will that stop or slow utorrent ?

MooseJam

dorsanty makes alot of sense i think it must be the router because it slows down my dads internet as well and he is on another pc, probably nothing can be done about it

Cabaal

autotuninglevel being enabled can cauee alot of problems with different applications on Vista depending on make and model of router being used

as such its often worth trying to disable it

If you go through the settings in uTorrent it lets you put limits on the number of connections it uses and stuff like that. I think that for a lot of the limits it even lets you set time ranges

so it does, it's currently set at 250, I can see how that would slow things down, i'll cut it back a bit, thanks for that

i have utorrent running on a different pc on the network and it still can cause slowdowns

i limited it to 100 conections max and 8kb/s up and its fine now, and it still downloads at full speed without hogging webbrowsing

I always wondered this actually....well, now I know.
