Ksmbd (Samba3/4 alternative, ex cifsd/smbd) package support thread

That is the right way to do it I guess.
Maybe bigger values (4MB/1MB) would be needed for faster 2.5/5/10G ports and WLAN 5GHz 160MHz - 2400Mbit/s.
But testing is the right way and it's good that we now know the reason for the speed limitation cap that we had.

I don't know how much memory the maximum consumes in an app scenario running, even if your device has 1GB size of RAM. If your app scenario uses almost 1GB of memory, You may need to adjust the smb2 max read/write size.

For my usual usage currently I don't see any memory penalty but of course if I see higher memory usage I'll report it.
Regarding the memory usage this @KONG's post maybe usefull too.

OpenWrt Support for Armor G5 (NBG7815)

FYI, this setting: sysctl -w vm.min_free_kbytes=65536 reserves 64MB RAM for the kernel and drivers. Without this setting an app could request mem until nothing is left, then kernel has no mem anymore to open new network connections, or connect new wireless clients even come to a complete stall. It does not matter if it is samba or any other app. I have seen things like this with samba before e.g. when a drive acts up drops, and suddenly you copy to routers ram.
