[] – Initialising password list… Read in 224 words from /opt/wordlists/fasttrack.txt [+] – Running with 10 threads… [] – Starting attack against username@10.10.10.10
[*] – Trying: 65/224

Test Run

# The password is in line number 12600 in rockyou
64 threads -> 1400 seconds ~ 7 minutes (hydra took 30 minutes)
1000 threads -> 464 seconds -> 27 requests per second
100 threads took 1000 seconds -> 12 requests per second
# the password is in line 460
100 threads took 32 seconds -> 14 requests per second
1000 threads took 16 seconds -> 28 requests per second
64 threads took 51 seconds -> 9 requests per second (hydra took the same time)
# word number 20k in rockyou
1100 threads took 637 seconds which means 31 rps
110 threads took 1457 seconds so that’s 13.7 rps

Uses a custom implementation of paramiko to overcome a few minor issues with implementing it for ssh brute forcing. – https://github.com/paramiko/paramiko/
