On my computer, running scrypt (N: 2^14, r: 8, p: 4) on the string "00x00x00x00x00x00" with the salt "abc" takes on average 0.12 seconds.
Do you know what kind of hardware would be needed to make this a thousand times, or ten thousand times, more efficient? (So that it would take 0.12/1000 or 0.12/10000 seconds.) How expensive hardware are we talking about? Millions of dollars, or less? Just looking for rough estimates.
