Astra Mini Performance problem (3fps)

Camera: Astra Mini
OS: Ubuntu 16.04
Processor: Intel i5-4300U @1.9GHz

When running the SimpleBodyViewer-SFML, MaskedBodyViewer-SFML, or MultiSensorReader-SFML example code it runs between 2-3fps. Other examples like ColorizedBodyViewer-SFML run at a smooth 26-30fps.

Is 3fps kind of performance that can be expected when doing hand or skeleton tracking?
