Rasa Docker 0.29.3 - Train Model only creating 40 % CPU load?

Hi, when Training my model via click on “Train”, i only see about 40-50 % cpu load on the machine via nmon, on Intel® Xeon® CPU E5-2680 v3 @ 2.50GHz with 8 logical cores.

Is there something i could do, to make it use all available cpu power and finish faster?

Any options on how manye cores can be used and at which utilization?

On a sidenote, i updated to 29.3 to check this, was using .28.x before. RASA_HOME variable is not respected on 0.29.x versions currently, install always ends up in /etc/rasa.
