so hashes/s is same as passwords/s?

cpu can't go that fast

Alot of hashes are cracked faster using a CPU over GPU actually. So it's a matter of what you're trying to use and what is being used. Otherwise, this command doesn't make sense:

hashcat64.exe -m 11600 -a 3 -?l?d hash.txt ?1?1?1?1

Unless you meant to do:
 hashcat64.exe -m 11600 -a 3 -1 ?l?d hash.txt ?1?1?1?1

And I'm guessing you're wanting to do an increment to your command as it sounds like you're wanting to guess all possibilities from 1-4 characters and not strictly to 4. Check out the Wiki for increments as that's probably what you're needing.

Here's a full example of guessing from 1 TO 4 Characters using LOWERCASE & DIGITS:

hashcat64.exe -m 11600 -a 3 -1 ?l?d -i --increment-min 1 --increment-max 4 hash.txt ?1?1?1?1?1?1?1?1?1?1

Even though I have a mask with a length of 10, the increment commands will limit it from 1 to 4.
Otherwise, h/s is the same as pw/s or guesses/s or hits/s or whatever you want to see it as.
