I can reach 10500 P/s in btcrecover on my GTX 1080, but even with an incomplete set of chars from the example passwords [Fromage243Md96?P15hyqz7TiltQus8!fjpOknwc0] it will take years to crack 8 chars.
Hashcat gives 8000 P/s (but not for this hash, I was trying to crack wallet with 1 BTC and unknown 11 char pwd in it that has 122023 hash iterations, so with 80062 speed should be around 12k P/s).
Longest sample pwd is 17 characters, bruteforcers can't event start bruting such passwords, either something overflows or it eats all the RAM
Good luck bruteforcing that
it says that extimated time is 3years and 61 days
Mine too, which must be incorrect, it should be around 32 years for my charset according to
http://calc.opensecurityresearch.com/a-zA-Z0-9 will take 700 years on 10k P/s.
