Hi Jamdrese,
Need one urgent help for memtest
Can you please share your code. I want to test it on my system?
I got your reference from below;

It's fun to benchmark memmove and memcpy on a box to see if memcpy has more optimizations or not. On Linux x86_64 gcc memcpy is usually twice as fast when you're not bound by cache misses, while both are roughly the same on FreeBSD x86_64 gcc.
Linux (2.4Ghz Xeon X3430):

./memtest 10000 1000000
memcpy took 0.575571 seconds
memmove took 1.082038 seconds

./memtest 10000 1000000

memmove took 1.442741 seconds
