this is not just about disk I/O; the M1 CPU is simply much, much faster
than the RPi4's CPU.  to provide some concrete numbers, i did a quick
benchmark using primegen[0].

on my desktop, an AMD Ryzen 7 5800X3D (amd64) running 15.0:

% time ./primespeed 10000000000 >/dev/null
./primespeed 10000000000 > /dev/null  3.66s user 0.00s system 99% cpu 3.679 total

on an RPi 4 running 14.0-RELEASE-p3:

% time ./primespeed 10000000000 >/dev/null
./primespeed 10000000000 > /dev/null  21.65s user 0.00s system 99% cpu 21.647 total

on a base (8-core) M1 Mac Mini running Darwin 23.2.0:

% time ./primespeed 10000000000 >/dev/null
./primespeed 10000000000 > /dev/null  4.27s user 0.00s system 96% cpu 4.422 total

this is a single-core benchmark, so we can conclude that an M1
performance core is nearly as fast as a Zen 3 core, while that same M1
code is 5 times faster than an RPi 4 core.  and bear in mind that in
addition to its 4 performance cores, the base M1 has another 4
efficiency cores.

again, my point is not to put down the RPi, which is a great piece of
hardware for what it is -- only to point out that, performance-wise, the
RPi and the Apple CPUs are really not comparable.
