Well, I have a core2 and I'd LOVE to get 4x speed improvement on memcpy(), which is probably the single most widely used function in all of C programming.

Also, any improvement to Atom performance can only be welcome.

I took a simple oprofile trace of me using my desktop for a while. Sad to say, but in that trace glibc's memcpy() used 0.24 % of time.
It would probably be better idea for majority of systems to just remove memcpy() and just replace it with memmove() which showed up with 0.17 %. Together, that would add up to 0.5 % at most, I suppose.
