Comment 11 for bug 196439

Normal downloads don't cause a problem, at least not here.
No, I tested it bare, firefox and apt-get or firefox and apport-cli

I have that one installed, I even set up the /etc/trickled.conf
I don't know if it's correct:
[firefox]
Priority = 1
Time-Smoothing = 0.1
Length-Smoothing = 2
[firefox-2]
Priority = 1
Time-Smoothing = 0.1
Length-Smoothing = 2
[firefox-3.0]
Priority = 1
Time-Smoothing = 0.1
Length-Smoothing = 2
[irssi]
Priority = 1
Time-Smoothing = 0.1
Length-Smoothing = 2
[wget]
Priority = 2
Time-Smoothing = 1
Length-Smoothing = 4
[update-manager]
Priority = 3
Time-Smoothing = 4
Length-Smoothing = 18
[apt-get]
Priority = 3
Time-Smoothing = 4
Length-Smoothing = 18
[update-notifier]
Priority = 3
Time-Smoothing = 4
Length-Smoothing = 18
[apport-cli]
Priority = 3
Time-Smoothing = 4
Length-Smoothing = 18
[apport-retrace]
Priority = 3
Time-Smoothing = 4
Length-Smoothing = 18
[apport-unpack]
Priority = 3
Time-Smoothing = 4
Length-Smoothing = 18

The bad thing with trickled is that the daemon doesn't autostart as a service on each boot. And it doesn't say if it should be run with sudo or normally
