Could I ask some thing off topic?
What faster to found address want VanitySearch program?
VanitySearch 1.19
Vanitygen 0.21
oclvanitygen
VanitySearch-1.15.4_bitcrack
Have you tried running a benchmark yourself? The very first post of this thread has some speed comparisons and tells you you can search for some uncompressed key as a test.
On my Intel Core i7-4770, VanitySearch runs ~4 times faster than vanitygen64. (1.32 Mkey/s -> 5.27 MK/s)
On my GeForce GTX 645, VanitySearch runs ~1.5 times faster than oclvanitygen. (9.26 Mkey/s -> 14.548 MK/s)
If you want to compare VanitySearch and Vanitygen result, use the -u option for searching uncompressed address.
My gut feeling is VanitySearch-Bitcrack may be slightly slower than VanitySearch but I never used that program.
For a pure vanity address finder, VanitySearch is hands down faster because of the symmetry and endo features PLUS you can look for compressed uncompressed, and the bc, 3, and 1 addresses.
VS Bitcrack is more about specific ranges although, you can search for Vanity addresses with it. VS bitcrack and VS are different animals, intended to do different things, but still have common features.
