You can lower your upload limit to say 24KB/sec then in tools > preferences > network tab if it bothers you that much.
I do find it hard to believe you are only getting 3KB/sec - try choosing the files with the higher score which represent the amount of people found in that search query with the exact same file.

p.s. thanks iamnacho for editing that and welcome aboard as mod to gforums. didn't know you were mod. good to know !
