Abstract

This paper presents a practical approach to automatically tuning the parameters of the Apache Web server. In particular, two significant parameters, KeepAliveTimeout and MaxClients, are dealt with. The notable features of our approach are twofold. First, it is easy to deploy because no modifications to Apache or the underlying operating system are required. Second, our approach is based on the detailed analysis on how each parameter affects the server's behavior. Experimental results demonstrate that our prototype works well on different workloads; it can discover almost optimal values and quickly adapt to workload changes.
