TCP and IP.  Having packets arrive out of order hurts fast-path performance.
the inherent requirement is to take a packet and put it into a holding
position until it becomes 'in order'.  The required checking and holding and
retrieving hurt performance.

If you know of a TCP implementation that does not take a performance hit with
