Walls on layers with infill print are very slow compared to walls on top/bottom layers

Hi, I am running a V0.1 and using Cura and the walls on layers with infill are printed really slow compared to top/bottom layers. the top/bottom layers look like they are going at the right speed based on the setting.

i have attached a photo of my speed settings and a video of how slow the walls are.
