That's why you are asked to use oprofile to find out. You may use
systemtap as well.
My readings shows that bash is slow here, not MC; your mileage may vary,
of course. But problems must be fixed where they occur, not where it is
convenient to put a hack for you.

I set up your locale, generated dirs via:
for n in $(seq 100); do DN="${DN}/notsolongdirnametotestnested_$n"; done; mkdir -p "./${DN}"
and I can move throught the end of this tree without a crash and with
some small slowdown (about 1-2 seconds in the end).
I use mc-4.8.3-36-gf1075b8 and bash-4.2_p37.
Best regards,
