Why uTorrent take half of my band ?

[darkon11]

uTorrent 2.0.2 resolved speed problems of the past releases but there's still something that I don't understand.

I have a band of about 700 KB/s and when Utorrent is in use (like now at 350 KB/s) the D/L speed of other programs (i.e. firefox) drops to 0.

At other speed the combined speed is about half of the band or less.

Bandwidth settings are:

Max. U/L speed 10 KB/s

Max. D/L speed 600 KB/s

Max. number of connections 500

Max. number of connected peers 500

upload slots 10

Is there some trick that I should know ?

Edit @ 21:10

In the meanwhile I made a test with the pretty old 1.7.7, the gap is still there but at 350 KB/s it leaves me a reasonable 200 KB/s.

Also try 2nd link in my signature.

Maybe I wasn't clear.

I don't have speed problem but it seems that uT 2.0.2 uses a lot more band than it shows.

Since 1.7.7 don't (with the exact same settings) I'd like to know why.

Oh, and just to be clear I have a 30/700 KB/s connection.

v1.7.7 didn't show approximate overheads it was killing in the background.

v1.7.7 also didn't use poor-router-overloading UDP packets nearly as heavily.

Thanks

What should I do to make 2.0.2 behave this way ?

[Switeck]

Turn off some of the new features...and lower your settings to reasonable rates for your connection.

I'm curious, what new features are you reffering to?

[Switeck]

Disable the old usual suspects: UPnP, NAT-PMP, DHT, Local Peer Discovery, and Resolve IPs.

Reduce bt.connect_speed to only 1-4, reduce net.max_halfopen to 4.

Disable uTP and also possibly Teredo/IPv6.

[darkon11]

Wow it's a lot.

I think that the best solution is to use 1.7.7 when I need band for other apps.

Thanks

v2.0.3 should use less bandwidth than v1.7.7 if you do this.
