Hello everyone,
I have just installed OpenWRT on my XIAOMI AX3600 router. I had no problems with the installation.
Everything works fine, only the speed of my internet connection is capped. On the original firmware, I'm at around 956 mb/s, whereas with the OpenWRT firmware I'm capped at 550 mb/s maximum, so I can't go any higher.
I've tried tweaking a few settings, but nothing works.
Any ideas?
That is about the maximum speed you will get from this hardware and OpenWrt.
The OEM firmware relies heavily on NSS based hardware offloading, which is not available on OpenWrt (you will find more detailed discussions about this topic via the forum search, use "ubicom32" and "NSS" as keywords). The current switchdev based networking drivers are very rough and basic, while there is a lot of untapped potential to improve those, that is not going to happen any time soon (or ever), due to the lack of hardware documentation and the mountains of work required.
Thank you for your reply slh,
I understand, so unfortunately there's no point in me staying on OpenWRT with this router, knowing that it halves my internet speed.
Best to read the whole OpenWrt page on the router before you brick it trying to go back to OEM.
I had already tested OpenWRT on this router 1 year ago when it was still in beta mode. I went back to the original firmware without too many problems. I hope it will be the same this time.
Question, I did some research on NSS and found several posts on the subject with screenshots of OpenWRT versions with NSS and speeds capping at over 900 mb/s.
Any chance then? Risk of installing custom firmware?

Look here IPQ807X NSS Build but can be unstable and it's not official.
thank you,
the versions available all mention "wifi", but the problem is also present in wired so we need to find a version with the NSS LAN + WIFI?
No, the wired version was working since some time ago. Now they are focusing to accelerate wifi too. The builds from the thread contain both.
Thank you.
I have try 3 versions.
For me the version [dimfish] : https://openwrt.admincomps.ru/nss-wifi/
work perfectly, i have 940 mb/s wired and 650 mb/s wireless 
with [starraiderx] version wired is ok but wifi problem
with [AgustinLorenzo] version wired and wireless ok, but in my ax3600 i have encoured problem with DHCP Server
