By reordering elements in dummy_packet_stream structure, sum holes
Do you mean "the sum of the holes" can be reduced or do you mean "some holes"

can be reduced, thus saving a cache line.
Before: structure size: 784, sum holes: 56, cachelines:13
After : structure size: 768, sum holes: 40, cachelines:12
