Yes, 2.4G is only a half speed of the previous version. I tested on my wndr3800ch and wndr3700 v4.

To keep it short, 2.4 GHz performance seems unchanged but down from r5442. 5 GHz performs worse then on previous build (r6150) but performs better then previous builds.
sotux:
Yes, 2.4G is only a half speed of the previous version. I tested on my wndr3800ch and wndr3700 v4.
With minstrel patch on wndr3800ch:
Since there have been more mac80211 commits what is the build number of the build you are testing?

@nbd Another person reporting a roughly 50% speed cut with the Minstrel patches. Yet @Bartvz reports unchanged performance. Perhaps it is client dependent? Is there anything else we can do to help pinpoint the issue further?

kmod-ipt-offload is for kernel 4.14, the fast path patch is
I have successfully ported Qualcomm OpenSourced Fast Path for LEDEN
Fast Path will work on ALL hardware
You don't need to configure any additional settings for Fast Path as long as modules are loaded successfully it will work
From my testing Fast Path improves Wireless and Wired Throughput
On my WDR4300v1 running at 730MHZ I can achieve Wire Speeds

I use this patch on kernel 4.9 for my netgear wndr3800ch & wndr 3700v4 because ar71xx is on kernel 4.9 now.

My custom build has included "netfilter flow offload" because the master branch include these commits. But I did not test it because I don't have these device relay on kernel 4.14. If you have the device that can run on kernel 4.14, then you can test it.

5G wifi seem's not affected no matter upload or download.
@sotux - is there any difference when targeting the router directly (there is already iperf3 there). This way will eliminate one of the computers.

Thanks for testing. Could you please also do the same test that @Mushoz did and delete the minstrel patches one by one in reverse order to figure out which one is having this impact?

OK. I tested again with each patches, below is the result:
Removed patch id
Download speed
Upload speed
329
19.9 Mbits/sec
66.3 Mbits/sec
329, 328
18.9 Mbits/sec
65.6 Mbits/sec
329, 328, 327
43.3 Mbits/sec
64.4 Mbits/sec
329, 328, 327, 326
42.7 Mbits/sec
68.2 Mbits/sec
So, I think the patch "327-mac80211-minstrel-merge-with-minstrel_ht-always-enab.patch"

@sotux Thank you very much for your testing. @nbd , It seems to be the same patch that's affecting me. The only difference is that in my case my upload speed is also affected, as can be seen here: Optimized build for the D-Link DIR-860L
If I can help testing with potential solutions for this regression, please let me know

Thanks for testing. After some more careful code reading, I was able to find the bug. I've pushed a fix to master, please test.

And now I just pushed some more minstrel fixes that should help on 2.4 GHz as well.

My build environment was dirty and was running into compilation errors, so I cleaned it and started anew with compilation, hence it is taking a while. Should I let the current compilation continue (without the latest commits) and test versus my previous tests in which I noticed the regression? Or should I abort the current compilation and pull the latest changes in?
For troubleshooting whether the previous regression was fixed, the current compilation should be fine, right? Since the bug fix was in commit: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=55bd80f6d871d1c6c70101579524c42cdb73ed7d
