Description of the problem (how to configure, how to reproduce, how often it happens).

Openwrt x86 installation on x86 hardware with Compex QCA9984 as wifi.
Testing scenario:
Sata connected SSD 120G, continuous transfer rate of 220MB/s read. file 10GB.
vsftpd daemon serving file
Two routers equally configured with two same sata drive and same file, same vsftpd conf, default openwrt config:

WRT3200acs : OpenWRT

36 channel , 160Mhz channel width, WPA2 - mvebu driver and firmware
Client: macbook 15" 2018 . - filezilla client
Client <-- WiFi << Router <--SSD
99MB/s
KANSUNG with Compex QCA9984 as wifi: OpenWRT

36channel,80Mhz channel width, WPA2 ath10kct driver 4.19 and firmware
Client <-- WiFi << Router <--SSD
72MB/s with firmware-5-ct-non-commercial-full-htt-mgt-11.bin or 10,9,8
52MB/s with any other firmware-5-ct-****
KANSUNG with Compex QCA9984 as wifi: OpenWRT

36channel,80Mhz channel width, WPA2 ath10k vanilla driver and kvalo firmware
Client <-- WiFi << Router <--SSD
60MB/s
KANSUNG with Compex QCA9984 as wifi: DD-WRT

36channel,80Mhz channel width, WPA2 ath10k vanilla driver and kvalo firmware
Client <-- WiFi << Router <--SSD
99MB/s
Software (OS, Firmware version, kernel, driver, etc)
openwrt- latest trunk

Hardware (NIC chipset, platform, etc)
NIC: Compex COMPEX WLE1216V5-20 5GHz
Platform: KANSUNG Model: K515G6

Logs (dmesg, maybe supplicant and/or hostap)
Why is ddwrt the fastest than any other openwrt distros? Which optimization is in ddwrt and not in openwrt. I got 2000softirq(netdata) kmod-ath10k utilization.

I would kindly ask for DDWRT developer to publicly release those tweaks for ath10k driver and other optimization to get 99MB/s in openwrt also.


Can someone pinpoint where could be the performance issue and which tools should i use to dig into it ?

Goran.

seems that there is some crucial change between those version, but u can not find what is changed:-(

Maybe some sharper eye can tell me what could be the cause of this download boost:

https://svn.dd-wrt.com/changeset?old=33607&old_path=src&new=33772&new_path=src

MUMIMO maybe?

Get on some more recent firmware, see my signature for links. (Latest at the moment is 41418.)
