Hashcat running VERY slow

They must be identical to make any conclusions.

$2a$05$

for instance means 2^5 = 32 iterations, but for instance $2a$19$ means 2 ^ 19 = 524288 iterations.

524288 is much more than 32, $2a$19$ is much slower than $2a$05$

the more salts you have, the more combinations there will be each salt must be combined with each password.

If you look here you can see what they are supposed to be: https://hashcat.net/forum/thread-5440-page-5.html

Its running at almost half the speed of a 1070's benchmarked speed almost everywhere.
