1/4 cpu cores being used

[skalderis]

My quad Q6600 always on 25% load while cracking, even after numerous hours of work. Had 5850 before running different version of hashcatplus, I know for sure back then cpu wasn't used. Now is. Win7.64, Cat13.1, 7970. Used driver fusion, reinstall - same. I paste output maybe you'll see something unusual. Like big hash file. Can that be the cause?

Code:

Plus I was writing this while cracking, windows was kinda lagy so BSOD popped up. Very nice blue color. Didn't saw that for a while. Point is after --restore i get "ERROR: cannot read oclHashcat-plus.restore". But that's another, sad story. Will leave that for another time.

Hashcat-plus is a GPU-based cracker. It is specifically designed NOT to tax your CPU.

i think that's his point, is that it is using 25% cpu when he feels he shouldn't be.

however, in this example he is cracking 13.8 million hashes. and while he didn't paste his command line, he's probably using --remove or some other switches that are likely driving up cpu utilization. with that many hashes, i would say this is probably normal.

@epixoip
Yes, I do use --remove. Probably lots of file reading operations. Thanks for reply.
