I'm limiting dropbox upload bandwith with trickle as suggested here.
@reboot trickle -u 100 ~/.dropbox-dist/dropboxd
This works great but unfortunately causes 100% CPU - even with only 2-3 (small) files in total. On its own Dropbox only consumes about 1-2% CPU (without trickle).
What might cause this CPU hog? Is there any other way to throttle Dropbox upload speed?
