I view mem=8G not speeding things up as a good thing, since one is looking for a solution allowing use of all 16GB of RAM.Great suggestion! Tried mem=8G. Unfortunately, no joy:As I see it, a possible difference between the 8GB and 16GB models is the D0 stepping of the latter. The new stepping is rumoured to be required for addressing 16GB RAM.
Is it possible something at the driver level adds the equivalent of a bounce buffer?
I'd try mem=8G on the Linux command line to see if that makes any difference. It may not.
Pi5-8GB N04: 2min 8sec (N04)
Pi5-8GB: 2min 20sec (X1001)
Pi5-16GB: 3min 35sec (N04)
Pi5-16GB (w/mem=8G): 3min 41sec (N04)

I wonder if changing the EEPROM from default to the latest would make a difference.
