[ath9k-devel] Performance degradation when monitor interface is enabled

[Ali Abedi <a2abedi@uwaterloo.ca>]

Thanks for the answers. The performance issue theory doesn't make sense 
as we get the same lower (and stable) throughput on different machines 
with difference CPU powers or when power saving mode is enabled/disabled 
(which changes CPU clock frequency) on this machines.
The interesting thing is that when I remove the monitor interface the 
throughput remains the same (low). Isn't this a bug?

Thanks,
Ali
