Seems to be mainly issue with Windows 10 clients than.
Windows is always a kind of an issue... 
Seriously, you can test with a Live Linux to see if the tests are better.
To clarify, my tests were not run during backup activity. I only brought up the part about backups to head off any comments about my speeds being "good enough for internet speeds."
Just for reference, I re-installed @quarky's NSS enabled build (17.01-SNAPSHOT r4075-54fc4f9050) which I had been testing some time ago. I still see the same excellent ethernet speeds, but WiFi is measurably better in terms of bandwidth. I ran the WiFi tests for 30 seconds to allow speeds to stabilize:

My concern, and next step for testing, is that the WiFi driver in this build will exhibit significant wireless bufferbloat since it's not using the ath10k CT version that has WiFi bufferbloat enhancements.
** UPDATE **
Just ran an internet speed test and my results match the same up/down speeds that I receive on an ethernet connection. I haven't seen my download speed (420 Mbps down) reach and hold that speed on WiFi in a long time. Also, I did not see any alarming increase in ping times during that speed test, so immediate concern re: wireless bufferbloat is looking minimal at the moment.
** UPDATE 2 **
The CPU governor is ondemand by default, so for giggles I am going to try to set it to performance and run the tests again...
I understand, but did you try a bidirectional test with iperf? You will probably not see 300Mbps in both directions at the same time.
I'm following now--sorry for my confusion there.
Here is what I see on a bi-directional iperf with @quarky's build:

iperf Done.
I think you applied -d thinking it is a bidirectional flag, but it is not the case for iperf3 that you are using (that was true for the old iperf).
iperf3 needs the one below and it has to be v3.7 or higher (you can use brew for MacOS to install it if you are using it.
--bidir run in bidirectional mode.
I'm using both Manjaro and Windows (see here: Slow 5 GHz downloads on R7800). Anyway the conclusion is the issue is most likely on Windows side. I suspect some latest update since a few weeks back the throughput was in par with Linux.
Right you are! Sorry about that--I was indeed using the wrong flag (old habits die hard)...
I updated my bi-directional testing post with the true tests. Feel free to take a look and see what you think. Thanks for the kind reminder about the incorrect flag 
Well, I was not getting results like that in 19.07 when I tested but the trend is the same: the combined throughput remains relatively the same.

To be thorough, I upgraded to @hnyman's r13022 build and ran the same bi-directional iperf test twice with the r7800 CPU set to performance governor:

After running some wireless bufferbloat tests on the @quarky firmware, it was significantly more latency prone under load than the latest @hnyman builds. I always test with Flent: The FLExible Network Tester and the @quarky build was 50ms - 150ms higher latency (and WAY more than that on the UDP BK test) across the cumulative sweep on ping_cdf and icmp_cdf plots.

Ok, I am trying to understand if your R7800 setup as an AP or a router?
My R7800 is set up as an AP. My pfSense box is my firewall/router. My NAS is attached to my R7800, though, since all my devices that back up to it are wirelessly connected.
Ok, so that explains it then: mine is doing NAT, firewall, PPPoE, and applying VLAN on WAN packets.
All that definitely adds some overhead in your scenario. But it still seems there is some slow-down that has occurred with WiFi from earlier versions of OpenWRT. I love my R7800, but it's letting me down as an AP lately. Got me looking at UBNT mesh setups.
Hi all! I want to share my experience regarding this issue.
My setup: running iperf3 from my NAS server and MacBook Pro (3x3, 1300mbps). OpenWrt official build 19.07 on R7800.
The problem: from NAS to MBP: 300Mbps; from MBP to NAS: 700Mbps.
My solution: (1) switch the WiFi firmware from -ct to non-ct (uninstall two ath10k-ct packages and install two ath10k ones), (2) disable irqbalance, (3) apply The CPU freq fix in R7800 wiki, (4) reboot the router.
After the reboot the iperf3 shows 700-800Mbps on both directions.
Note that for me the irqbalance will reduce the speed from 700 to 300 again, thus I disabled it.
Related issue on ath10k-ct repo: https://github.com/greearb/ath10k-ct/issues/138
Same issue here with R7500v2.
Any solutions?
