Very high "runtime" value with -w 4 - patpro - 06-07-2017
Hi,
I'm currently running hashcat 3.40 on Ubuntu 16.04 LTS with a single GTX 1080.
My hash file is about 20M SHA1 hashes, and I'm using mask mode:

HWMon.Dev.#2.....: Temp: 82c Fan: 56% Util:100% Core:1809MHz Mem:4513MHz Lanes:16I'm using this hardware for several weeks now, and I can't recall reading such a high value of "runtime" : about 2 seconds.
Yesterday, I've ugraded the whole system, Nvidia's driver included (yielding to a +20% perf gain on SSHA-1 bench for example). I've also installed Ubuntu-desktop.
I wonder if that very huge 2 sec. runtime value is due to one of these software changes.
And by the way, despite the -w 4 option, the desktop looks responsive.
here is the nvidia-smi reading:

Is the runtime value correlating with some kind of other performance problem?
Also, any reason why you're not using a newer version of hashcat?

Hi Royce,

My post is pretty old, I've upgraded HC since.
And no, the ~2sec runtime value does not correlate with perf problems, but using -w 4 is supposed to yield to an almost unresponsive GUI (for example). I'm not seeing any performance drop on this area, and that whats bugged me :)
No big deal anyway, everything looks ok.
