you're comparing platforms here. I think FreeDOS EMM386 is the main
program which influences transfer speeds.
You might try setting up an environment where only kernel is different
and see how that affects things.
Use freecom, FreeDOS lbacache/tickle/himem/emm386 and switch between
IO.SYS/MSDOS.SYS and KERNEL.SYS
At any case, switch only one component at a time :)
Strange to see that cache delays things
