Throughput drop with ath10k latest driver and firmware-5.bin_10.2.4.70.66

[KAVITA MATHUR]

Hi,
 
In my AP , there are two radios, one ath9k based module WLE200NX and second ath10k based
WLE600VX.

I configured both the radios as AP in IEEE 802.11a 40 MHz HT mode and performed
throughput test.

Measured throughput with ath9k is 164Mbps while with ath10k it is 137Mbps. I could not
understand the reason of this drop(27 Mbps)? 

My test setup was inside RF-Shield. There was no interference and system was associated
at 300Mbps in both cases.

ath10k driver was taken from ath10k git and firmware version is
firmware-5.bin_10.2.4.70.66. 
ath9k drives was taken from stable backport release backport-4.4.2-1.

kernel version : 3.12
openwrt version : Chaos Calmer 15.05.0

Please suggest me how can I increase the throughput of my AP.
