I'm not sure where the speed is in the G-code:

Looks like the Z move from pierce to cut height is at 20 then everything else is at 10. F stands for Feedrate and stays active until a change. It can be appended to a motion command but takes effect before that move. I bet 10 is kinda slow for that cut.
