Switched back to the latest Docker Beta to keep performance tests current – as of 1.11.0-beta8, this is still a pretty severe problem. Running the same test suite in the beta as dlite, the beta runs in 72 seconds, dlite 22.
CPU usage difference between the two is extremely considerable. The beta pegs my CPU while my tests run, while dlite is barely a blip in top.
Hoping this can be overcome!
