Really? ...
Do you have the links to the faster ones?
The groundwork was laid a long time ago.
https://github.com/Telariust/VanitySearch-bitcrackFaster, with multi gpu support. Take existing code and make the tweaks one wants/needs. Much easier to understand and tweak vs bitcrack, IMO. Pool operator can verify that it is faster as well. It also supports the newer cards, 30xx series.
yes, it faster
my test
VanitySearch is faster
I am not sure can compare or not with method search for bitcrack and vanitysearch
