For clarification, I'm assuming you're using a 20MHz channel?
What firmware?
What mode - TDD, PTP, ePTP?
UP/Down ratio or Flexible?
What MCS up and down is it most often using?
Did you try iperf with '-u' UPD flag and/or '-r' to test up/down independantly? Not saying that's a better test, just saying the comparison might be informative.
I didn't have 'E-mail me when someone replies' checked, so I didn't see that you had responded. Thanks for the reply and sorry for my delayed response.
Yes, 20MHz, thanks.
Firmware: 2.4
ePTP mode
Up/down ratio of 50/50
Attached are the MCS readings... I think this is pretty strong, right?
I did do with -u flag, but I did it at a limited bandwidth (~30mbps bi-directional) to see what non-max-load latency looked like. (I'm interested in maximum TCP performance, so the UDP performance is not of interest for max load.)
Yes, I did do '-r' also, and was able to achieve ~58mbps (IIRC) in each direction like this. The limiting factor comes when I try to do both simultaneously. (The test machines are able to get 1,883 mbps aggregate across the switches being used, so it shouldn't be the test setup).
I think that I may be reaching the limit of the radio... I just want to make sure I'm not missing anything.
