Excess CPU use when application should be completely idle

Description (last modified by dkocher)

Cyberduck (v 3.2 4648) has two windows open, both simple FTP (port 21, one anonymous, one non-anonymous). These connections are -- or should have been -- idle for several DAYS. All I'd done after opening the connections was to list a directory and then hide the application.

The Cyberduck application windows were in the background ("Hide" from Dock menu) and the application had not been selected as a foreground application for several days.

Yet I see cyberduck.app consuming up to 7% CPU -- which matters on a battery-powered laptop -- to do *nothing*.

Perhaps this is just a bad Java implementation, but perhaps there's something in the Cyberduck application which can be fixed.

I can't really explain this. One possible cause could be Rendezvous/Bonjour activity on the network (services appearing and disappearing). You could try if it makes a difference with Bonjour services discovery disabled for Cyberduck using 

defaults write ch.sudo.cyberduck rendezvous.enable false

Thanks for the quick suggestion. I've added that preference and I'll report back if I still see idle application CPU cycle consumption
