I had been using dlite with litlte to no issues. Switched over to Docker Beta 6-7 hours ago. The entire time, CPU usage has been running at max. Nothing more than an nginx server with a mounted volume for the web app. Had to turn off my laptop in between to let it cool off.
The Docker Beta is completely unusable at this rate but everything else about it is great.
Surely, this has to be a known issue unless I got really unlucky with my setup.
