I still don't think that's likely to be the problem. I was able to reproduce 100% cpu usage with 0kb/s transfer speeds, and I've consistently seen it with transfer speeds below 100kb/s. "Stop Downloads, but finish running ones" will drop cpu usage to normal levels no matters the transfer speed, whether that's 100kb/s or 20mb/s. This seems tied to heavy dns request activity.

Here's the log I just was able to make:

17.04.20 17.58.41 <--> 17.04.20 18.00.25 jdlog://7587815302851/
