is bcrypt´s benchmark showing bcrypt itterations or bcrypt hashes per second?

If I run the benchmark it advertises:

sudo hashcat -w 4 -b -m 3200
[sudo] password for gpu-user:
hashcat (v4.0.1) starting in benchmark mode...

* Device #1: GeForce GTX 1660, 1486/5944 MB allocatable, 22MCU

Benchmark relevant options:
===========================
* --workload-profile=4

Hashmode: 3200 - bcrypt $2*$, Blowfish (Unix)

Speed.Dev.#1.....:    9308 H/s (148.01ms)


Does H/s now stand for brypt itterations or for bcrypt hashes?

Since it just says $2*$ I think it is single itterations and not bcrypt-hashes the cost factor usually comes behind this like $2a$05$ which would be 32 itterations.

Now any post I find about the topic bcrypt benchmarks is saying it being bcrypt-hashes and not itterations and that the bcrypt cost factor for the benchmarks is 5 so my GPU would produce 32 x 9308 itterations per second.

I searched this forum and many others all containging that info

https://hashcat.net/forum/thread-1737-po...ml#pid9885

https://security.stackexchange.com/quest...ing-bcrypt

and many more


But now when I benchmark using a own list of hashes I get results that are pretty way off the expected result.


$2a$16$ is 65536 itterations
$2a$05$ is 32 itterations

so $2a$16$ should take 2048 times as long as $2a$05$

if this is really not itterations but cost 05 bcrypt hashes :
Speed.Dev.#1.....:    9308 H/s (148.01ms)
then with cost 16 I should expect about 4.5 cracks per second

but if I try it out it takes much longer:

^^^4 minutes for 6 hashes and hashcat itself also predicted that time.

But that means the benchmark is really showing itterations not bcrypt hashes or am I doing something wrong?


Here is a list of hashes for reference to test with: pwd: donotqwerty
