Since I am working with Dist. 13.04 I am experiencing much background traffic. I have a monthly limit of GB to down or upload. So it is burdening my balance. What I have done up to now: 1. I have switched of Ubuntu One from automatically synchronizing. But it showed no improvement. 2. I switch on and off my internet connection according to my work. So I just have connection if I want to work in the internet. That has reduced heavily the daily background traffic balance but it is nasty. It wasn't necessary before. I could stay online all the time without much background down/upload.
What else can I do?
