For those of you testing sp's new release(s), show comparison test, not just speed.
How would that work though? By posting a bunch of speeds reported from different programs, you're still relying on taking their speed at face value.
To see whether sp_ really did speed up the program and not simply multiplying the counter by 4 or 5, we must test it with a small range, such as 0 to 5 billion, which we can expect to finish in about 5 seconds on the regular Bitcrack on some GPU that does 1000MKeys/s.
If the mods are genuine then it will finish in about a second (again, I can't do this myself because no source code => no way to compile on Linux aaaaargh

)
