Hi guys, i have an AP connected to a Aruba 650 OS Version 184.108.40.206, i am running a jperf test with 2 computers, i connected an AP105 to the controller port G1/3 and the VAP is configured on the 5Ghz band (40 Mhz wide channel) , the wired client is also connected to the controller port G 1/4. I am running a jperf server on the wired station and the jperf client is running on the wireless station and i can't get more that 50 Mbps. Below a few commands that i had run to troubleshoot.
I can see that the client is connected using 40Mhz short guard interval 2 spatial stream and the client is connected at 300 Mbps.

Can you share the chipset, wireless client driver version etc? Could you please enable BCMC on VAP profile and also on VLAN to re-test again to see how it goes. What happens if we have a on more client connected direclty to the controlller and do the iperf test between wired devices connected directly to controller, then connect the same client on uplink switch same VLAN wired and again do the test. By this way, we get throughput on wired devices, wired to wireless , uplink switch wired to compare the results.
(sri-7240-xm) #configure terminal wlan virtual-ap default
(sri-7240-xm) (Virtual AP profile "default") #broadcast-filter all
Warning: broadcast-filter arp should be enabled with this option. Otherwise ARP requests will be dropped!
(sri-7240-xm) (Virtual AP profile "default") #broadcast-filter arp

Enter Configuration commands, one per line. End with CNTL/Z
(sri-7240-xm) (config) #interface vlan 10

To get a better throughput
- run JPerf with UDP (TCP give you less throughput because of the windowing)
- use an open SSID (encryption and decryption process slows the throughput)

Sorry for my late response, i tried everything you suggested and when i plugged both devices to the WLC gigabit ports i started to see better performance, then i changed the downlink from the WLC to the switch and that definitely help. Then i connected a AP225 and the TCP throughput is way better.
