A new session would be necessary to run more forks that you can
interrupt and start again. The POT file has lots of your previous
cracks already, if you weren't specifying a mode, John would of done
all the same work it did before, and simply not crack anything new
until the 20 forks passed the work the 5 did previously. Even if you
specified a different POT, the same passwords would of been cracked,
it would look like John was doing something, but it was the same work
as before.The POT file saves the cracked hashes and does not attempt
to crack the same hashes. John tries all hashes with each guess, so
until John surpasses where you left off with the 5 threads, you won't
have any new cracks when running the same command. If you ran a 20
minute session with 5 forks, the 20 should of caught up in 4-5
minutes, or 24hrs, in 6 hours, ideally. I think :)
