Hello,
we're using a PCIe AR9280 card on a Octeon MIPS CPU. The system
that does the transmission has a high CPU utilization:
iperf in UDP mode with 50M bandwith has ~90 % CPU utilization with a
high softirq proportion.
Using an Intel card (5300) has a lower CPU utilization (~60 %), but it's

Are you using the ath9k rate control or are you using minstrel_ht? My
tests were done with minstrel_ht. You can enable it by disabling the
config option for the ath9k rate control.

This is interesting. I have a problem with rate control (I guess) too. Can you
give me a clue on

I'm using 2.6.38.1 ath9k which is at ~80 % CPU, starting from 2.6.37.1
with ~90 % CPU which was still an improvement. Do you think that
compat-wireless gives still a performance boost?
Not sure. These numbers sound awfully high to me.
