Hi,
I found and packed an optimized version of memcpy/memmove ready to use for linux clients or linux servers into libmemmove.so. This code gave me between 10-15% boost improvement on copy operations on an other project handling 20+Gpbs of data and I think it could be worse the try to test how it would do for ns2 binaries. If you are planning on using it please post some bench in here.
