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?

@krowe No: that thread provides other techniques to achieve the same thing, but doesn't address why this particular technique doesn't work. –  Gilles Jul 6 '14 at 23:11
What versions of trickle and dropbox do you have? Have you checked their bug list? What distribution are you using? –  Gilles Jul 6 '14 at 23:12
