Overextrusion at my seams. Motion seems to pause.

I'm working on printing nylon. So I have my speeds dialed down to 60mm/s for the most part. However, it seems like the motion pauses at layer change or retraction and ends up causing a bit of overextrusion. Where is the parameter in Prusaslicer that drives this speed? I've been digging and can't seem to puzzle out which knob needs to turn.
