Hi,
I am testing AR9342 Throughput with 20Mhz channel bandwidth, using
OpenWRT/LEDE firmware.
However, the throughput result is quite low. About 65Mbps to 70Mbps while
the bitrate is 144Mbps.
While testing I monitor the CPU usage and it's still free for about 30%.
Is it the best it can do? How to improve it?
Thanks,
Dat

How are you testing this?
On an 9580 using iperf and sending in the VI queue i get around:
TCP: ~94Mbit/s
UDP: ~122Mbit/s

I did TCP test within RF boxes.
The results seems right to me because my AR9342 is 2 streams and I can get
65-70.
With your 9580, If I am not wrong, is 3 streams, you can get up to 95.
However, I am going to test 9558 to see how much it can go. I expected 2
streams 20Mhz to get around 90Mbps.
Thanks,
Dat

Dear experts,Has anyone has the throughput numbers for AR9287? On a 802.11g (20MHz), I could measure < 20Mbps with iPerf.And are the below measurements done in an anechoic chamber free from other WiFi traffic and only 2 clients (source and sink for iPef) connected to a WiFi AP?Regards
Sandeep.

These numbers are with 2 streams.
With 3 streams i get
TCP: 140 Mbit/s
UDP: ~180Mbit/s

Thank you for your information, I did another test for AR9342 and the
result is quite good compare with what you get.
AR9342 - 20MHz
TCP: 90 Mbps
