Improving web server performance using two-tiered web caching

Abstract

The purpose of this study is to improve the web server performance. Bottlenecks such as network traffic overload and congested web server has still yet to be solved due to the increasing of internet usage. Caching is one of the popular and efficient solutions to reduce network latency. However, there is a need to study the current caching technique and further optimize the result. Therefore, this study proposed a Two-Tiered Caching System (2TCS). The 2TCS adapts a selective caching system concept which contains two tiers in its caching architecture. The 2TCS is used to further increase the probability of achieving a cache hit on top of utilizing the normal caching system. The proposed technique utilizes SQUID as its web cache server and also Mozilla Firefox's default caching system at the client side. A performance comparison of a normal caching system against the implementation of the 2TCS is made using the IBM Rational Performance Tester to prove the result
