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.

Thread: Proper Airflow and Case Selection
Post: RE: Proper Airflow and Case Selection

7990 on top with a reference 6970 on the bottom works fine, h... |

That's a nice increase on the descrypt, a little disappointing on the md5crypt though! |
