I am by far no expert. But all your buffers reside on the heap and introducing a extra copy to m_buffer introduces another chance to trash the cash. I wouldn't worry to much about the stack data, it's only some pairs of ptr/length that would even fit into the registers.
cachegrind is a linux tool for cache simulation.
