The　increasing　network　throughput　challenges　the　current　network　traffic　monitor　systems　to　have　compatible　high-performance　data　processing.　The　design　of　packet　processing　systems　is　guided　by　the　requirements　of　high　packet　processing　throughput.　In　this　paper,　we　depict　an　in-depth　research　on　the　related　techniques　and　an　implementation　of　a　high-performance　data　acquisition　mechanism.　Through　the　bottleneck　analysis　with　the　aid　of　queuing　network　model,　several　performance　optimising　methods,　such　as　service　rate　increasing,　queue　removing　and　model　simplification,　are　integrated.　The　experiment　results　indicate　that　this　approach　is　capable　of　reducing　the　CPU　utilization　ratio　while　improving　the　efficiency　of　data　acquisition　in　high-speed　networks.
