Dear Thomas,

I am able to find the embedded boards with Gigabit Ethernet, so the
throughput measurements are as followed:

Non Secured Mesh (HT40+)
# iperf -s -i 1
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ ID] Interval       Transfer     Bandwidth
[SUM]  0.0-10.5 sec   189 MBytes   151 Mbits/sec

Secured Mesh (HT40+)
# iperf -s -i 1
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ ID] Interval       Transfer     Bandwidth
[SUM]  0.0-10.9 sec  23.7 MBytes  18.2 Mbits/sec

So more or less the throughput for HT20 and HT40+ for secured mesh is the
same, not much improvement. Perhaps, due to processing overhead for using
the software crypto in the setup (nohwcrypt=1).

What's the throughput that you able to get in your site? Any network cards
that is able to support hardware crypto acceleration in Mesh setup?

Please advice. Thanks

Regards,
Chun-Yeow
