RouterBOARD and QoS

Hi guys,
I’ve been doing lately some traffic shaping and prioritizing VOIP traffic on RB433AH on some AP and what I noticed is that the performances of RouterBOARD dropped down so much… :frowning: is it common behavior of the RouterBOARD when it comes to QoS?
Anyone have same problems? What should i do?

Thanks
