Keyhunt with bsgs is giving me 1 Exakeys/second speed. Its 1,000,000,000,000 Megakeys/s in 125 bit range which is quite impressive, Its almost identical to searching 66th puzzle with decent gpu. Correct me if i'm wrong.
what's your system? gpu ? cpu?
Its combined 6 Google 300$ trial vm instances of 16 core cpu 64gb ram, and plus my pc. Each vms get ~160-180petakeys/s. Eventually google trial will expire, but worth to try.
My pc i5 12500F cpu with 32gb ram can take 50Petakeys/s.
Keyhunt is only cpu, resource, electric cost friendly option out there.
