Very high "runtime" value with -w 4
#1
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:

I'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:
