You made me dig up my own Pi4 to check that the correct function is called, and it is the memcmp.S variant, not the generic one.
I'm also running the tests anew under aggressive active cooling, just to be sure, but Dave also had some active cooling on hi Pi and seems to think throttling is highly unlikely.
(meanwhile the pi3 results might have run into a failing SD card...)
