Hash Numbers Effect Speed?

[Uraniumhazee]

I a fan of hashcat.
First sorry for my English.
I have a question.

For example i have ve 1.16800 file
I collected 150 pmkids.
What is the difference between crack single pmkid and put 150 different Wifi's pmkids in to the 1.16800?
Cracking speed changes? and why not changes?

Another example
Yesterday i put tons of md5 hashes into a *.hash file and tried an 12 Gigs worlist for it. It was very fast.
If i had tried single hash, wolud the speed has changed much?
If not?

What are the difference between try on on hash and multi hashes at the same time?


Thanks for your replies.
