the qca8337 can be treated as a dumb switch which is connected to a single mac interface. so 1 gbit for all ports. there is nothing to accelerate here. in between the ports the switch is self managed so traffic is passed betwen the ports. but everything which goes to the router or is routed by wan passes a single ethernet mac. but combined all switch ports can only archive 1 gbit alltogether
quick test
