Without the details of your setup, it's difficult what you are doing to claim this low performance.
So , weekend with rain, and covid-19 lockdown, plenty of time for a little experiment.
I have no 2nd hAp ac2 or ac3, so I have to do it with a free Omnitik ac (single CPU, weaker in performance than a hAP ac2), I used only the router not the WLAN which is not so good indoor.
As my hAP ac2 is in use, I have to test it with the current settings (5180MHz-20MHz ce) a 40 MHz wide band (max interface rate is 400Mbps). The Omnitik is on the first floor , so separation is far from ideal with the concrete floor in between, but this gives me a send speed and a receive speed of 240 Mbps.
But extrapolation is dangerous. So when nobody was using the hAP ac2 I changed the setting to (5180MHz-20MHz Ceee) a 80 MHz wide band. This is the real test.
The Omnitik is reachable over a powerline connection , so I split of the WLAN1 from the bridge on the Omnitik, and give it a different IP address.
Over that Powerline (Devolo) the Btest shows 45 Mbps. I know Btest on the routers is far from ideal, but always a bit lazy.
Receive test initiated from the Omnitik over the WLAN connection. I manipulated the Omnitik to behave as a hAP (allow indoor freq, TX power high as a hAP).
The signal is somewhat in balance. -57dBm is good enough, 49 dMn SNR, low CCQ 67%/75% is what you can expect with that floor.
The data flow is a steady 345Mbps , although the P throughput is 518 Mbps

Now time for a send test from the Omnitik, also giving 355 Mbps

Maybe it is the CPU of the Omnitik that gets overloaded, or getting too much interrupts. (80+% load, 30 000 packets/s , FP not used on transmit !?)
So when receiving in the hAp ac2 the non-FP load is still on the Omnitik.
360Mbps and 30K packets/s .... 10Kb packet size !? What does A-MSDU (=MPDU) and A-MPDU do here ????

And one more, sending from powerful hAP ac2. Not really an improvement 400 Mbps.
Remember this setup is far from ideal ! Getting tuned results would be easy (no floor, higher basic rate, remove the 5 SSID from the hAP ac2, stop my other AP's in the same channels, ...)
hAP ac2 better than 200 Mbps: Q.E.D.
My benefit: will integrate the Omnitik WLAN as replacement of the Powerline connection. 8 times faster.
