Fast way of copying byte array in C/C++ (With measurements)

UPD 2017: these are early experimnts on c++ compiler optimizations. I don’t think it is useful any more. I have the following code for copying several buffers from one object to another: 1 2 3 4 5 6 7 8 9 // Copy several buffers (images) for( int i = 0; i < MIN( conf_.size(), src.conf_.size() ); ++ i ) { // Copy pixels for( int j = 0; j < MIN( sizeOfBuffer_, src....
