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.
