Movement during certain sections of G-code is slow (CNC)

I just finished building my first DIY CNC. I modeled a simple part and did the CAM on it with Fusion 360.
I uploaded the G-code on CNCjs and started the program (after positioning everything). The program seemed to go correctly except when it needed to do arcs between straight movements. Arc movements seemed to be super slow (about 0,1 mm/s). I have tried to increase junction deviation (tried so far 0 and 0.003) and acceleration (20 mm/s^2 and 30mm/s^2) but it doesn’t seem to help. I also have chosen in Fusion 360 “selected configuration” as Smoothie since I use Smoothieboard with recent CNC firmware and config.
