Hi all,
I did a simple test with Kraken and received 2 different results about
performance of Kraken (see below). For the first test, the cracking process
took
about 92s. For the next test with the same input, the crack took only 8s. The
difference was too much. Is it normal? How can I improve the performance
(software, hardware)? Could anyone give me some advise about the best
configuration for Kraken? (GPU model, memory, CPU...)
Thanks,
David
