Testing AP performance - speedflex questions

[david_lipkin]

I have three APs - 720, 720, 710. They all are running POE and are configured as mesh even though they have ethernet connections. I have a number of questions:

- if I run AP-AP speedflex will I get a result that is via ethernet or wireless? currently I only see ~320 up and down with this test. I'm concerned that I have a wiring issue since I'm getting such low performance. 

- I'm considering moving to 1-2 R750s and some 350s at the edge. Should this switch to 802.11ax improve performance? What's the expected AP to client performance with 802.11ax?

- I understand that problems with POE can produce lower than maximum transmit power. What transmit should I see? I'm not getting alerts.

- What's the maximum throughput from AP to client that I should expect? I can't get better than ~320 on 5G.

- Often I see it recommended to separate the SSIDs for 2.4 and 5Ghz. Will that improve performance for the Ruckus devices or is it unnecessary. 

Thanks for the help.
