Please share the real throughput you saw. To check the status during you do scp test, please enter debug entry of this driver, and capture log by: /sys/kernel/debug/ieee80211/phy0/rtw89$ while [ 1 ]; do cat phy_info; sleep 2; done | tee scp_test.log Then, send the result to me. If there is privacy problem, please send private mail to me directly. Also, you can try 'iw wlan0 set power_save off' to see if it helps.
