I want to restrict the upload speed of my transmission client to 1kB/s, is it possible?

What changes do I need to make to lower the upload speed?

Edit-> Preferences -> Transmission Preferences -> Speed Limits/Alternative Speed Limits

Under Speed Limits/Alternative Speed Limits you can set what the max speed your data needs to be uploaded.

Alternate way

open gedit $HOME/.config/transmission-daemon/settings.json

"speed-limit-up": 5, "speed-limit-up-enabled": true

You can set "speed-limit-up" to your desired number.

great, if I lower the upload speed will it actually make my downloads faster? – Ankit Aug 23 '12 at 3:59
Nope. Not really. It doesn't affect your download rate. – devav2 Aug 23 '12 at 4:08
thanks.. does this mean that i will get maximum download speed (according to my bandwidth) irrespective of the whatever upload limit I have. – Ankit Aug 23 '12 at 5:23
@devav2, I beg to disagree. If his upload limit is set too high, he might be using too much bandwidth for transmitting data (and on some DSL upload bandwidth is very scarce!), hence delaying the transmission of TCP ACK for the data he is downloading, therefore slowing down his own download speed. – fdierre Aug 23 '12 at 9:26
@devav2 that's exactly the point! If the download bandwidth is much higher that the upload bandwidth, then you will need a significant percentage of your upload bandwidth just for sending ACK to the data you're downloading, and so you must be very careful with uploading other data. Been there, done that: I can choke my ADSL download speed anytime, by just not setting an upload limit. :-D – fdierre Aug 23 '12 at 9:45
