yes, it faster


my test
VanitySearch is faster

I am not sure can compare or not with method search for bitcrack and vanitysearch


brichard19 BitCrack ==> 11 MK/s

Bitcrack-sp-mod1 ==> 50 MK/s  (full memory)
Bitcrack-spmod2 ==> 50 MK/s

VanitySearch-bitcrack ==> 70 MK/s

VanitySearch ==> 149 MK/s

command test
VanitySearch.exe -gpu 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN


VanitySearch-bitcrack
GPU: GPU #0 GeForce GTX 1050 (5x128 cores) Grid(40x512)

VanitySearch

problem
VanitySearch fast but it search full key 265bits
can not search by keyspace for puzzle #64


Original VanitySearch uses endomorphisms to perform fast additional checks for each key generated.
For each key it checks K, K*lambda, K*lambda*lambda -K, -K*lambda, -K*lambda*lambda - total 6 possible addresses.
So, for original VanitySearch speed means addresses per second, not keys per second.
These checks are not needed to find addresses in the range. That is why BitCrack and Vanity with bitcrack mode is much slower.
