Abstract
In this paper, the architecture of kernel-mode and user-mode web-servers and the constraints that affect their performance are studied. A set of experiments have been performed to measure and analyze performance of kernel-mode and user-mode web servers on an open source Scientific Linux CERN platform. Web servers under study include kernel-mode TUX web server and user-mode Apache web server for varying static workload sizes. The results of the experiments revealed that the performance of kernel mode web servers greatly exceeds to that of user-space web servers.
