Thread: Slow VCL performance
Post: RE: Slow VCL performance
| Thanks for the reply- I will compare performance with a lower -n value. Would there be any value in going to VCL 1.21?
I noticed that I didn't mention this is a brute-force attack, by the way.
I gue... |

Post: pw-skip / pw-limit

Thanks! |

Thread: Slow VCL speeds
Post: RE: Slow VCL speeds
| Just for the record- I've managed to get ~20 000K/sec over gigabit using VCL, which is the speed I was expecting all along. The trick was ramping up the -n value way up- anything under 300 or 400 was ... |

Thread: Slow VCL speeds
Post: RE: Slow VCL speeds
| If I watch top, the oclhashcat process just consumes more and more memory, starting at ~15%, and steadily consumes until all is exhausted. The rate is about 2%/hr, if I remember correctly.
