I have two RB 751U 2HnD's (Upgraded to the latest firmware).
I have them setup as wifi bridges (also in mesh mode, planning on expanding this with more on the way) - and am getting around 20-25mbits/sec TCP throughput according to iperf
On the interface status it shows them connecting at around 108mbits each way (sometimes one side bumping up 150Mbits). Taking away some IP and TCP overheads I should be getting better than 25mbits/sec shouldn't I? I am wondering if I am missing something obvious.
RX/TX strength is showing at (-56/-37)
Noise floor is -118dbm
Tx CCQ is around 90-100% most of the time
I did a 'fast as possible' ping between two end points - results below:
--- ping statistics ---
10000 packets transmitted, 10000 received, 0% packet loss, time 17769ms
rtt min/avg/max/mdev = 1.036/1.426/13.010/0.853 ms, pipe 2, ipg/ewma 1.777/1.437 ms
CPU usage peaks at 40% during a large transmission.
I'm happy to provide further details. Any hints or points would be fantastic.
