A study on performance evaluation of K4 Firewall System with multiple CPUs and security rules

K4 방화벽의 CPU 및 보안규칙의 증가에 따르는 성능평가연구

According as development of networks and increasing on Internet service, For the performance increase of K4 Firewall require that hardware be installed of 2 CPU or 4 CPU instead of 1 CPU. Output of performance test among 1CPU, 2CPU, and 4CPU of K4 Firewall system has not any efficient about increasing multiple CPUs. K4 Firewall put performance on setting on demon of packet filtering rules and Network Address Translate and Authentication and Proxy services. Performance results that setting after security rules are less 2％ Packet Filtering, 8％-11％ NAT, 18％-20％ Proxy and Authentication services than setting before security rules on K4 Firewall System. NAT and Proxy service have decrease of performance. This performance result comes in useful for research and development on K4 Firewall System.
