Did something change between version 6.1.1 and 6.2.4 regarding -S option - walterlacka - 10-03-2021
I noticed that when using version 6.2.4 and the command:
hashcat.exe -m22000 -O -w4 -a0 -S d:\ftp\hashes2021\test.22000 d:\ftp\wordlist2017\rockyou.txt -r c:\hashcat-6.2.4\rules\best64.rule
It runs normal at first, but then the speed decreases as time goes on. It seems like it slows down for a bit, then speeds up again, but overall the performance is less than in version 6.1.1
Version 6.2.4:
Starts out like this:
Speed.#1.........: 624.7 kH/s (231.70ms) @ Accel:64 Loops:1024 Thr:512 Vec:1
Speed.#2.........: 437.4 kH/s (239.79ms) @ Accel:64 Loops:1024 Thr:512 Vec:1
Speed.#*.........: 1062.1 kH/s
Candidate.Engine.: Host Generator + PCIe
Then after a few mins:
Speed.#1.........: 68212 H/s (233.75ms) @ Accel:64 Loops:1024 Thr:512 Vec:1
Speed.#2.........: 200.5 kH/s (251.49ms) @ Accel:64 Loops:1024 Thr:512 Vec:1
Speed.#*.........: 268.7 kH/s
Candidate.Engine.: Host Generator + PCIe
Whereas, with version 6.1.1, it's very consistent the entire run:
Speed.#1.........: 576.1 kH/s (232.11ms) @ Accel:32 Loops:1024 Thr:1024 Vec:1
Speed.#2.........: 413.4 kH/s (254.60ms) @ Accel:32 Loops:1024 Thr:1024 Vec:1
Speed.#*.........: 989.5 kH/s
Maybe it's an Auto-Tune thing? I noticed that the Accel/Loops/Thr values are different between the version in the results above.
When not doing -S with version 6.2.4, it runs consistent:
Speed.#1.........: 553.9 kH/s (360.76ms) @ Accel:64 Loops:1024 Thr:512 Vec:1
Speed.#2.........: 389.6 kH/s (366.72ms) @ Accel:64 Loops:1024 Thr:512 Vec:1
Speed.#*.........: 943.6 kH/s
Candidate.Engine.: Device Generator
Thank you
