Performance of copy algorithm

[Dhruv Matani]

A) Open coded loop on char			 7.20s
B) memcpy					 0.80s
C) Loop using doubles				 1.68s
 (cheats on alignment and block size)
D) memmove					18.96s
E) std::copy (which translates to memmove)	18.96s

I have just copy pasted this form a post in the past.

I'd like to say, that on my system (RH-9, 2.4.20-8), memmove 
is _*actually*_ faster than memcpy!!!!! That comes as a surprise to me.
