I have WLC which controls a WLAN that hosts data traffic and VoIP traffic.
I have enabled Platinum QoS profile and the throughput of the WLAN decreases to approximately 10 Mbps (With bronze QoS profile throughput was like 22~25 Mbps).
I would like to know how does the QoS profile limit the throughput of the WLAN? WLC gives a warning that data traffic will be affected but that doesn't tell much about the actual mechanism of traffic limiting.
I used iperf software sending UDP data @ 500 Mbps to measure the throughput.
