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.
